To set the temperature lower you must click the button on top to take the temp higher and then after 92 degrees it will start again at lowest temp of 67 and you can increment from there.

What kind of fish tank heater do I need for 300 gallon tank?
By Customer Service on January 12, 2012

Answer:
Greetings Alex,

Depending on the average room temperature and desired water temperature we suggest two 300 watt heaters or two 450 watt heaters.

If there is anything further we can do for you please let us know.

By Mark Flores from San Diego, CA on January 23, 2012
Will this 300 Watt heater be ample power to heat a 100 gallon with no problem? I realize that on the description it says tanks up to 100 gallons. But you know how some products say state that and in the end it doesn't deliver. Anyone out there have a 100 gallon aquarium that has this running in their aquarium? Feed back would be greatly appreciated. I'm trying to avoid running 2 heaters. Thanks in advance.

Answer:
Greetings Mark,

We have a very informative blog that will be able to better assist you regarding how to choose the appropriate heater. There is a section specifically written to help users understand the variables when choosing a heater for their aquarium.

One tip: If you are at the higher end of the capacity rating move up to the next size or double up.

If there is anything further we may do for you please let us know.

great heaters
April 15, 2012
This is my second aquatop heater from tru aqua. I love these heaters. The displays are easy to use. They have easy to see indicator lights showing whether the power is on or off, whether or not the heater is active, and an exact temperature. They reliably activate and heat the water as soon as it drops within 1 degree difference of the desired temperature. They are easy to set and use. And the temperature probe is set away from the heater for better temperature readings which also eliminates the need for a seperate thermometer. If i had to make a suggestion for improvements i would ask that the lead on the temp. probe be a little longer to get it a bit further from the heater on the 300 w as i did not have a lot of room to move it away from the heater as far as i would have liked too. However it is still a very effective and user friendly unit and i will be purchasing any heaters from aquatop from now on.
Pros:
Easy to Use, Effective, Safe, Good Value
Best Uses:
Small Aquariums, Saltwater Tanks, Freshwater Tanks, Large Aquariums

Nice product
March 3, 2012
This is a nice little heater with a thermometer that is wired into the heater, but has about 6 inches of wiring to locate it away from the heaters body. One button setting from I believe 64 to 95 degrees F to cover all needs. Press the button on the top once and the heater goes into setting mode. Each press moves the temp up one degree. Stop at the desired temp and you are done. Easy to read digital display that tells you the heaters setting and the tanks actual temp. I have this in my 55 gallon freshwater and it seems to work flawlessly. The only weak point is the power cord is about 2 feet shorter than what I needed to reach my power strip which is on the floor directly behind the tank that is sitting on top of a cabinet. Not really a big deal if you have a short extension cord available.
Pros:
Good Value, Easy to Use, Effective
Cons:
Power cord too short
Best Uses:
Medium tanks

Very hi tech heater and easy to use
January 28, 2012
I have a 75 gallon hex and this is the right size for it being that it's a very deep tank. The heater is very large so it needs alot of space. It's extremely easy to use. Only one button on the whole thing ! It keeps the water temp very accurately. If the temp drops it automatically kicks back on to heat it to what I have it set to. Great product!
Pros:
Durable, Safe, Effective, Easy to Use, Good Value
Best Uses:
Large Aquariums

Perfect 300w heater
November 24, 2011
Great value and it work much better than other 300w heaters that I have in the tank. Prior to the true aqua heater my temps on the 175gl tank would swing wildly but now the true aqua has everything dialed in. The digital thermometer and target temp are great - you can tell what it's really aiming for.
Pros:
Safe, Good Value, Effective, Easy to Use

Advanced but Simple to Use
July 29, 2011
The D2HT-300 Heater is not only sweet looking but simple to install and operate. The all black looks good in an aquarium and tends to blend into the background better. The dual read-out display makes it easy to read current aquarium temp as well as the set temp. The secondary temp probe ensures you are getting an accurate and thorough reading of aquarium temp. I recommend this heater for anyone who needs a new heater or would like to upgrade.
Pros:
Good Value, Retains Preset Temp, Effective, Durable, Secondary Temp Probe, Dual Read-Out, Easy to Use, Safe
Best Uses:
Saltwater Tanks, Freshwater Tanks, Need to upgrade the old, Large Aquariums

AQUATOP Digital Heater

The D2HT Dual Digital Display Heater from AQUATOP

By David Lass, Aquarium Fish Int'l Magazine, December 2011





The new digital heater from Aquatop Aquatic Supplies includes a number of features and benefits; it is an excellent aquarium heater.

CLAIMS: Aquatop claims that the heater is easy to use and will maintain the aquarium temperature correctly.

TESTS: I tested a 300-Watt Aquatop Digital Heater on a 50-gallon planted tank. Over a few weeks, I raised the water temperature by 2 degrees every other day and then lowered it 2 degrees, going from 70 to 80 degrees Farenheit and back down.

RESULTS: The heater performed perfectly. I confirmed each adjustment with two thermometers in the tank. the display on the heater clearly shows the set temperature and the actual temperature. It is easy to turn the heater on and off, and to make temperature adjustments. The heater itself is well-made, with suction cups for mounting it to the glass. I especially like that it has integrated temperature probe that is mounted 6 inches or so from the heater, which I think is more accurate than relying on having the sensor within the heater itself.

CONCLUSION: The Aquatop Aquatic Supplies Digital Heater is an excellent piece of equipment, and I encourage hobbyists to use it. It is easy to use, accurate to within 1 degree, well-made and sturdy.
