How Does the CF-400UV Canister Filter Work?
Unfiltered aquarium water enters the CF Series Canister Filter and passes by the UV sterilizing bulb flowing down the stack of vertical cylinder cutouts to the bottom of the CF Filter; then water is pushed up through the filtration media compartment; the bottom compartment first, the middle compartment second, and the top compartment third. The filtered aquarium water then returns from the CF canister back into the aquarium.


The CF-400UV canister filter also includes a built-in 9 Watt UV sterilizer to help kill algae spores and bacteria, promoting crystal clear water.

By Henna from Texas on September 20, 2012
Hi,
I want to set up a 28 gallon reef aquarium and am wondering if this filter would work or if it would create too much water movement.
Thanks.
By Customer Service on September 26, 2012

Answer:
Hello Henna,

We have received your recent product inquiry regarding the installment of a CF400-UV canister filter on a 28 gallon reef system. The CF400-UV has on estimated output of 370 GPH and would yield a turnover rate of approximately 10-13 times and hour. This is well suited for a reef system.

If you have any additional questions please do not hesitate to ask.

By Trevor from Boise, ID on April 27, 2012
What kind of surface skimmer can be used most easily with this filter?
By Customer Service on April 27, 2012

Answer:
Hey Trevor,

Good question! The input for the addition of a surface skimmer has an approximate diameter of 1/2". Most surface skimmers for aquariums include extra fittings and adapters providing a universal application. TOM makes a good surface skimmer and can be picked up for about 10-12 bucks. It might be a good idea to have a 1/2" plastic hose clamp handy or maybe a zip tie just in case the surface skimmer's hose diameter is larger than the canister's surface skimmer input.

If you have any further questions please do not hesitate to ask.

By Danette Doucette from Fredericton, New Brunswick. on September 30, 2012
I have recently purchased this filter for the thought to use it in a freshwater tank. We have since decided to delve into the wonderful world of saltwater and are in the process of making lists of things we will need. We do still have a freshwater tank we can use this system on but in the interest of saving money would love to be able to use it for our saltwater tank. We will be starting out with a fowlr system but will eventually want coral. How is this canister set up for salt filtration. It is my understanding that a skimmer is required and optimal. The tank is 70 gallons will this provide sufficient filtration etc. Any further info would be appreciated.
By Customer Service on October 8, 2012

Answer:
Hello Danette,

We have received your recent product inquiry regarding a CF400-UV. We understand you are currently using the unit on a freshwater setup but are interested in eventually using your CF400-UV on a 70 gallon saltwater setup. The unit will perform well on a 70 gallon saltwater aquarium. The majority of saltwater aquarium systems utilizes protein skimmers. They are not mandatory but they help a lot. They reduce overall maintenance by removing organics from a saltwater aquarium system and in the long-term improve overall health of a marine system.

If you have any additional questions please do not hesitate to ask.

By John from USA on January 17, 2012
I purchased the CF-400 and was wondering how often I have to change the Media..I have a 55 gallon Saltwater Aquarium with 7 fish..Thanks
By Customer Service on January 18, 2012

Answer:
Greetings John,

Great question. There are many different thoughts and theories surrounding filtration maintenance.

Filter Pads and Sponges are considered mechanical filtration media and should be rinsed as frequently as possible and replaced when they show signs of wear or breakdown.

Depending on what type of chemical filtration media you choose to use, we recommend following the manufacturer's guidelines in regards to recharging or when to replace.

When biological filtration media such as ceramic rings or bio-balls become laden with debris and organics they should be rinsed in a fish safe container with aquarium water.

If there is anything further we may help you with please let us know.

2)-my tanks is 20gallons so how long i have to change the carbon,bio ball in ceramic ring
please aswear to those cuestion because is so importan to my
GALLITOYOUKNOWME@HOTMAIL.COM
By Customer Service on January 23, 2012

Answer:
Greetings Sigfredo,

The CF400-UV Canister Filter comes with three fine, white filter pads and one coarse, blue filter sponge. Chemical and Biological Filtration Media can be purchased separately at www.TruAqua.com under the Filtration Media section (http://truaqua.com/aquarium-filtration-media.html).

Activated Carbon is good for roughly thirty days and should be replaced thereafter. The general rule of thumb is one cup of Activated Carbon per twenty gallons of aquarium water.

For Biological Filtration Media, Ceramic Rings and/or Bio Balls should never be replaced. Both should be rinsed with aquarium water in a fish safe container when they become laden with debris and organics. Keeping the Biological Filtration Media clean will lead to a healthy and efficient population of bacteria.

If there is anything further we may help you with please let us know.

By Tuz Xiong from Bellingham, WA on January 25, 2012
How do the bio rings and bio balls work? Do they naturally grow bacteria by themselves? If we go with the rings, what should we do with the other levels? Do we put the rings in all of the levels? If the UV light kills bacteria, how does the good bacteria remain in the water? I want a algae eating fish, so would the uv light kill off the algae it eats?
By Customer Service on January 29, 2012

Answer:
The bio-balls and ceramic rings provide good places for bacterias to grow. Your filter should include the following stages of filtration (in order).

1. Physical - which include filtration pads that filter through the debris in the water.

2. Chemical - which use carbon to filter.

3. Bio-filtration - which use bio balls or ceramic rings which grow bacterias.

So you can put the bio-filtration in 2nd level basket. Some people especially Japanese companies that switch the order of bio-filtration and chemical filtration order, they believe the bio filtration should be the 2nd and then chemical filtration. This theory is still under test and there's no scientific data to prove which one is better.

The UV sterilization include this filter only kills the algae floating in the water (thus cause the water to be muddy and green), in the process it may kill the bacterias too, but it won't kill any algae and bacterias which grow inside your tank (rocks, plants....). From our experiments and customer feed backs, the UV do an excellent job to make your water clear and could lead longer time between water changes.

By sue schlomer from rapid city, sd on May 23, 2012
I bought the bio balls, carbon and ceramic rings, but I do not know where the bio balls go, I know the carbon goes on the 2nd basket and the rings go on the top basket. Please help
By Customer Service on May 23, 2012

Answer:
Hello Sue,

We recommend stacking all of your biological filtration media in the top filtration compartment. If you have extra space in the top filtration media compartment you can add the Bio Balls in with the Ceramic Rings.

If you have any further questions please do not hesitate to ask.

By Jorge from Colombia on May 29, 2012
hello:
can I use this filter for an aquarium of 500 liters (132 to 133 gallons)??
By Customer Service on May 30, 2012

Answer:
Hello Jorge,

We have received your recent product inquiry regarding the CF400-UV canister filter with an integrated 9W UV Sterilizer. The unit is rated for aquariums up to 125 gallons. The CF400-UV is not suitable for aquariums larger than 125 gallons. The addition of either two CF400-UVs or one CF500-UV would be better suited for aquariums larger than 125 gallons.

If you have any further questions please do not hesitate to ask.

By Schmichael from Austin, TX on June 12, 2012
Q1) What is the wavelength of the light emitted by the UV lamp?
Q2) What is the lifetime of the UV lamp?
Q3) Does this filter have any indicator to show the worn out or failed UV lamp?
By Customer Service on June 13, 2012

Answer:
Hello Schmichael,

We have received your recent product inquiries regarding the UV Bulb included with AquaTop's CF400-UV Canister Filter.

A1)The wave length of the UV bulb is approximately 254nm.

A2) The approximate lifespan of the UV bulb is 8,000 hours of use. We recommend changing UV Bulbs every 6 months to ensure quality performance.

A3) The filter does have a UV indicator. The indicator is located next to the UV's ON/OFF switch. When the UV Sterilizer is ON the indicator glows blue. When the UV Sterilizer OFF the indicator does not emit light.

By Tina from Ohio on June 14, 2012
I have this filter and am wondering if anyone has the problem I do. It sounds like my filter is "sucking air". I know the water level is low but it does this even without that issue. Suggestions?
By Customer Service on June 14, 2012

Answer:
Hello Tina,

We have received your recent product inquiry regarding a CF400-UV. If it sounds likes your unit is sucking, that is probably what is happening. The Input Set is made up of segmented pieces. If any of the joints or connections are not submerged or exposed to air there is potential for a small air leak.

We recommend filling your air aquarium to the top which should submerge the entire Input Set. If all the connection points of the Input Set are submerged your filter will not suck air.

If you have any further questions please do not hesitate to ask.

By Jasmine from USA on February 22, 2012
My name is jasmine and I am really interested in purchasing your cf-400
canister filter! Although I do have a question. I was wondering what the
time of penetration is of water flowing through the UV portion of the
canister?

By Customer Service on February 22, 2012

Answer:
We have received your recent inquiry regarding time penetration of the CF400-UV Canister Filter. Time penetration is a very difficult calculation. If you are willing to do the math here is the basic information needed to figure this out.

CF400-UV Canister Filter Specs
370 GPH @ 0’ of Head
UV Light - 9W @ 30,000 mW/cm2
UV Light and Sleeve Distance - less than 3cm
UV Light Length - 5”

Here is a basic formula regarding true turnover
9.2 x gallons in tank
flow rate in gallons per hour [equals] # of hours for one turnover
If there is anything further we can do for you please let us know.

By Schmichael from TX. on June 21, 2012
Hello, I've got 2 more questions:

1) Is there a switch to separately control the UV light? I want to shut the light but keep the filter running especially when I've medication in the tank. I think I've seen a switch that controls the UV light some place online but decided to ask to be doubly sure.

2) Where do I find the wavelength of the UV light from the bulb installed in the filter? I've asked this question before and got an answer from you, which was "approximately 254nm." It's not that I don't trust you but the word "approximately" did not satisfy me as "AT LEAST 254nm" wavelength is needed for the UV light to be germicidal. Anything less than that is useless. Could you point me to any manufacturer paperwork so that I can see it for myself?

Thanks
By Customer Service on June 21, 2012

Answer:
Hello Again Schmichael,

1) Both the CF400-UV and CF500-UV have a power switch that allows you to turn the UV Sterilizer ON & OFF independently of the motor. The ON/OFF switch is located on the top of the unit. Located next to the ON/OFF switch is a UV Light Indicator. When the unit is on the UV Light Indicator glows blue.

2) We understand your concern regarding the wavelength of the included UV bulb. We are confident in our UV Sterilization products and we are more than willing to spend a few minutes with you over the phone to ensure you purchase a product well suited for you and the intended application.

Our normal our of business are Mon-Fri 9am-5pm

By Dave from Hatboro Pa. on December 31, 2012
I just bought this filter a few days ago. I have been out og the hobby for some years and just decided to get back in when I found a great sale of tanks at my local pet retail store at $1.00 a gallon. So I decided on a 55 gallon at $55.00 and a full wooden hood at a clearance price of $10.00 For $65.00 I just had to dive back in. I am awaiting my order to arrive in the next few weeks and will be doing a fresh water tank. For the time being anyway. Couple of questions. The retailer told me that the use of under gravel filters is a thing of the past. Is this true? Even if I decide to switch to salt wouldnt I want an under gravel filter? I understand this is a powerful filter but wouldnt I still want to keep my gravel as clean as posssible with out having to do gravel suction cleaning? Isee you do not sell under gravel filters OR the suction pumps for cleaning the gravel. So what would you use? I want my setup to be as permenent as possible. Now once I go to fresh water can I switch to salt with this filter and tank setup just by changing over the water and the fish maybe adding a proteen skimmer? I know there is a few questions but I want to do it right the first time and have never had a tank without an under gravel filter.
Thanks in advance
Dave
By Customer Service on January 4, 2013

Answer:
Hello Dave,
Welcome back to the world of aquatics! It’s true that under gravel filters have become relatively out dated, not to say that they are not functional. It seems the vast majority of aquarists have gotten away from under gravel filters for various reasons such as aesthetics and the growing use of sand. I would not advise against using an under gravel filter as it makes tank maintenance easier and requires less frequent gravel vacuuming. We do sell our PH series of power heads that can be used to run an under gravel filter with ease; however, you need to match the diameters of the power head and uplift tube accordingly.
The CF-400UV will have no problem handling salt or freshwater, and the intake tube of the CF-400UV can be adapted to work in conjunction with a protein skimmer. You would have to devise the necessary accessories for your particular protein skimmer, but it can be done. Also, the CF400 intake tube has a capped off additional input that could very well be used to power an under gravel filter as well. We have not personally tried it but it would definitely be feasible depending on how much suction you will need for your particular setup.

Can the CF400 be run on it's side horizontally? I know it's kind of a long shot but my aquarium stand is short and doesn't have room to accommodate a very tall filter. Thanks.
By Customer Service on July 3, 2012

Answer:
Hello Jay,

We have received your recent product inquiry regarding a CF400-UV and mounting/installing it horizontally. Please do not install the not horizontally. This will lead to serious issues not limited to leaks. Canister Filters are to be installed right side up and on a level surface.

If you have any additional questions please do not hesitate to ask.

By Yusif from Sarasota, Florida on July 6, 2012
Hello
Can I use this filter for an aquarium of 10-20 galons?
By Customer Service on July 6, 2012

Answer:
Yusif,

We have received your recent product inquiry regarding the use of a CF400-UV canister filter on a 10-20 gallon aquarium. You can absolutely install a CF400-UV on a 10-20 gallon aquarium. Do we recommend it? That all depends on what you are trying to accomplish. 370 gallons per hour is a fair amount of flow. On a 20 gallon aquarium a CF400-UV will most likely make your aquarium look like a freshly shaken snow globe. If you wouldn't mind sharing additional information regarding your aquarium set-up and aquatic goals we'll be better suited to assist you.

By lynn from mankato,mn. on January 7, 2013
will this work for 40 gallon breeder tank with 3 fancy goldfish?
By Customer Service on January 9, 2013

Answer:
Hello Lynn,
The CF-400 canister filter will likely over power your 40-gallon tank alone, let alone a breeder tank. Consider using the Aquatop CF-300 canister filter with a lower flow rate. You will need to take preventative measures on the intake tube to keep your baby goldfish from getting sucked up by the filter. We recommend stuffing the strainer with a coarse sponge material.

By brandon from dubuque, iowa on January 13, 2013
I am considering purchasing this canister filter 400 UV - however I'm curious

Would the 370 GPH be to much for my 29 Gallong Reef Tank w/ 10 Gallon refugium sump / overflow box
( The protein skimer is on the sump, I have slower swiming fish, red mandrins & sea horses) I've used an intake refugium box for my return line from the sump & that is harmless - with the spray bars to spread the return do you feel it would be overwhelming or detramental to my tank???

One last question please : pest anenomeos Glass or apiesta - will the 9w UV help stop those from spreading???
Please reply
By Customer Service on January 18, 2013

Answer:
Hello Brandon,
The CF400 aquarium canister filter may be too powerful for your tank setup. Using the 29-gallon capacity of your tank and the 10 gallon capacity of your sump, you will be cycling your tank about 9.5 times per hour. A better alternative would be the CF-300 Canister Filter http://www.truaqua.com/aquatop-canister-filter-cf-300.html, paired with the IL10-UV inline sterilizer http://www.truaqua.com/in-line-uv-sterilizer-10w.html. This particular setup will be better targeted towards your tank parameters and will cycle your water approximately 6.5 times per hour offering a more moderate flow rate and higher potency in the UV setup. A slower flow rate combined with a higher wattage UV will help to manage free-floating pathogens and algae blooms, especially in a saltwater setup. The UV targets the water that passes through the filter and then by the UV bulb. If you have surface contaminants you may need to place your fish in a quarantine tank and then scrape the walls or corals in your tank and allow for the filter to pick up the free-floating debris. Once the water clears up, it is highly advised to clean your filter pads and then begin normal operation of your tank.

Thank you,

I've got a reef aquarium with a large sump. Can I install this filter for flow in and out of the sump?
By Customer Service on January 31, 2013

Answer:
Hello Steve,
The CF series of aquarium canister filters is not designed to run inside of a sump as the flow rate into the sump must match or exceed the flow rate of the canister. If you find that your flow into the sump is over 370 GPH, the CF400-UV may work quite well on your setup.

Thank you,

Hello
How often must I clean this filter?
Thank you

By Customer Service on August 6, 2012

Answer:
Hello Yusif,

We have received your recent product inquiry regrading routine maintenance of a CF400-UV. We recommend rinsing the filter pads and sponges as frequently as possible and replacing when they show signs of wear. Replacement pads and sponges can be found at the link.

http://www.truaqua.com/mechanical-filtration-media.html

If you are using chemical filtration media such as activated carbon, we recommend following the manufactures guidelines. Replacement activated carbon can be found at the link below.

http://www.truaqua.com/chemical-filtration-media.html

Biological filtration media such as ceramic rings should be rinsed in a fish safe container with aquarium water. This should be done whenever the biological media is laden with organics. If you need more biological media it can be found at the link below.

I bought this canister filter with no UV sterilizer (because I am a novice and the retailer's service was poor).

Anywho, is it possible to buy the UV sterilizer parts post-purchase?

By Customer Service on August 10, 2012

Answer:
Pat,

W have received your recent product inquiry regarding a CF300. We understand you'd like to add a UV unit to the canister filter. Unfortunately you can install a UV unit into/inside of the canister. We do sell many UV products which may suit your request.

An in-line type can be installed on the run of plumbing going to and from the canister and aquarium. In-line units can be found here.

http://www.truaqua.com/in-line-uv-submersible-uv.html

We also offer submersible UV units with pumps. These would be install as separate devices. They can be found here.

We hope this helps. If you have any additional questions please do not hesitate to ask.



By Michael from USA on April 13, 2012
Greetings!

First, thanks for the most amazing and super quiet product, your CF400UV.

Wow - I really don't think I could ever go back to a Marineland filter again! Thanks so much!

The only thing missing - is a good handle. At my age, 65, and with my difficulties, bad back, this is way to large and heavy to be toting around without a good handle. Please consider adding a nice swing up handle by which to carry the canister please. Like a good bucket! In fact - I have the canister filter sitting in a nice 5 gallon bucket to move it when necessary.

Questions:

1.) The flow rate is just a bit too high. I really should have bought the 300 but wanted the UV Filter ability. Would it be alright to install a valve in the output line to create a little bit of restriction in the output? I am using just one spray bar, or half of the kit provided, due to restricted space, and about a 10% restriction in the hose diameter seems to balance everything out perfectly!

2.) Any problems with running a couple bags of Seachem Purigen or De-Nitrite in the filter. Amazing results from Purigen!

Thanks!

By Customer Service on April 13, 2012

Answer:
Greetings Michael,

We Thank you for the positive feedback regarding AquaTop's CF400-UV canister filter. We are happy to hear that you are satisfied with the unit's performance. The CF Series is one of the best sellers. Regarding the addition of a handle; we will most definitely pass this advice along to the product engineers of AquaTop Aquatic Supplies.

Hear are the answers to your questions.

1) It is possible to add a ball valve to the output of the unit. A little bit of added pressure to the output should be okay. The restriction of output would be translated as additional head pressure and should not effect the unit's long-term performance.

2) There are no problems with adding additional filtration media such as Purigen of De-Nitrite. Those are great products and will only enhance the over filtration of your CF Series canister filter.

If you have any additional questions lease do not hesitate to ask.

CF400 Canister Filter
January 18, 2013
I have a 55 gallon tank that was getting a little green and cloudy using a simple topfin 40 filter. I bought this to more appropriately clean my aquarium and within a week I had clear water. I use carbon, ceramic tubes, and plastic bio balls in conjunction with the UV lamp. Supper quiet, water trickling into the tank is louder than the pump running (I had to feel the sides of the filter at first to ensure it was actually running). I would definitely recommend this to a friend. The only thing I don't like about it is the type of black plastic used for the input and output of the water directly in the tank, it seem to be of lower quality, but so far it has not made a real impact on anything.
Pros:
Needs Little Upkeep, Quiet, Effective, Easy To Clean

Top notch filter by far!
July 6, 2012
I set up a 37 gallon tank with live plants and tropical fish. I had two filters going to keep it clean and clear. I was also using a bunch of medications. Once I got this filter and went through the easy setup my tank became crystal clear. I have not had to use meds except when adding new water or fish. This filter allows me to have the tank I have always wanted without all of the hassle. It allows me to focus more time on my fish and not the purity of my water. This was the best purchase ever! I am in the process of building a pond and I plan to purchase this filter again to ensure all of my hard work shows continuous, beautiful results by having the best filter out there. I received superior value and made a great investment.
Pros:
Powerful, Reliable, Durable, Effective, Quiet
Best Uses:
Tropical Fish, Small Tanks, Large Tanks

wow how annoying and noisy
July 6, 2012
I use this filter for my 30 gallon aquarium it cleans my water realy good but its to noisy and it takes a lot of room.I have it behind a cabinet in the living room and I can hear it alot.I can even hear it when the TV is on.But it realy gets annoying at night you can hear it all through the house, just a loud humming.I am probably going to replace it with something that doesn't make noise like a refeugeum.
Pros:
Easy To Clean, Realy crystal clear water
Cons:
Makes to much noise, To tall, Loud, Vibrates to much
Best Uses:
Outdoor Ponds, Clean water

Good bang for the buck
June 16, 2012
Bought this for my wife's 40. She'd been having algae problems,etc. probably from nitrate overload from the mollies that can't quit breeding. This replaced a hob filter that was noisy and just wasn't doing the job. While this model may have been a bit of overkill size wise for a 40 it works!! Water has never been clearer and fish are more active. Reasonably easy to clean - but if you have it running on the floor it gets heavy and a little awkward to move around. Self primer hasn't worked yet but that's reasonably trivial in my estimation. Quiet and effective is my experience so far.
Pros:
Effective, Quiet
Best Uses:
Larger Fish, Large Tanks, Tropical Fish

Impressive water clarity, and so QUIET!
May 4, 2012
I could not be more pleased with my purchase of this CF400UV canister filter from TruAqua! Installation on my 55 gallon tank was as simple as I expected. I found it necessary to soak the ends of the water supply hoses in very hot water for about 20 seconds, to make them flexible enough to install onto the pump fittings. Simple to load its generously-sized baskets with filter media, simple to assemble, seal, and prime, NO LEAKS or DRIPS WHATSOEVER! The pump is remarkably quiet, which was a relief, because potential noise level was an important consideration for me due to prominent placement of the tank in my home. Seems to be an excellent quality product throughout, attractive and practical design, no gimmicks or shortcuts detected. The tank's water is so remarkably clear, using this pump has actually contributed to my increased enjoyment of my hobby. I am so pleased with this filter, believe it to be a TREMENDOUS VALUE and HIGHLY RECOMMEND IT to anyone.
Pros:
Quiet, Needs Little Upkeep, Easy To Clean, Effective, Durable
Best Uses:
Large Tanks, Larger Fish

Excellent value and functionality
April 28, 2012
This a a great combination of filter and UV sterilization. I had previously purchased the CF500UV for my 90 gallon tank and was very impressed. That is why I purchased the CF400UV for my smaller tank. The water clarity really improves quickly with these filters. The water quality also benefits from this filter. It is very quiet to run. Cleaning the filter is very easy. So far I have no real complaints. It would be good to have more options for the outflow instead of just the spray bar.
Pros:
Effective, Easy To Clean, Quiet, Good combo UVFilter, Needs Little Upkeep
Best Uses:
Small Tanks, Large Tanks

my experience...
April 27, 2012
I do not usually write reveiws but... I am so impressed with this canister filter that I actually now own 2 of them!! I am running them on a reef tank, one with additional biological filtration and the other with a small amount of chemical filtration when needed. the one with biological filtration has been running for about 3-4 months now and is still as quiet and works as well as the day i received it. the uv sterilizer bulb works well also, but does burn out every 1.5 ish months but are reasonably priced to replace. I have had other canister filters before and they worked good as well but the cost vs. filtering capability was definately a lot higher with the other filters. but anyways... great filter for the price and if you are even the least bit skeptical, try it out... its only 100$ which in this hobby is very inexpensive!!
