Aquarium Heater Digital Dual Display - 300W

I bought this after my other heater died. It has been a reliable performer and a good looking unit. It is extremely easy to adjust the temp, just a push of the button. This was well thoughtout.

Purchased the 300 Watt Digital Heater For My 55 Gallon Aquarium. Very Easy To Install, Very Easy To Set Up, Very Accurate. I Will Be Buying Another One For My 150 Gallon Aquarium. I Want To Add That The Product Was Packaged Very Well And Shipping Was Really Fast. Buy From These Guys They Are Great.

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.

I own a 55 gallon freshwater tank and this heater does the job really well and is power efficient.

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.

The heater is very easy to use, after having problems with another heater. I decided to buy the one from this site and I have to tell you, the best I own.

This heater was perfect for my 65 gallon aquarium

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!

USE IN A 85GAL SOUTH AMERICAN CICHLID TANK.CONSISTANT & ACCURATE TEMPS ARE KEPT AT ALL TIMES. EVEN IN TOTAL DARKNESS AT A GLANCE YOU KNOW THE TEMP! I NEED ANOTHER FOR MY 55GAL TANK! GREAT PRODUCT & WILL BUY AGAIN!!

Now I have 5 of the Aquatop D2HT servicing 5 of my 12 tanks. 1--300w--1 200w and 3 100w and all are working fantastic!- Ready to switch over all the rest of my tanks!

The dual display is very nice. Makes it very easy to monitor current temp with designated temp.

Installed heater, works great,temp steady.

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.

This is my 3rd heater from AQUATOP--all digital dual I have 12 tanks going from 5gal-55gal Very disappointed in Marineland Stealth heaters especially after recall. Searching for a better heater at a resign-able price and found it in AQUATOP. Accurate within 1 degree +or- I plan to use them in the rest of my tanks!

The product is installed in a 93 gal saltwater tank and set for 77 degrees. It works great and so far I have had no issues. I really like the LED readout.

Just a sleek attractive easy to use heater. Keeps water temp within a degree.

Placed in my 75 gallon freshwater tank, it keeps the temp as stable as i have ever seen it. Doesnt seem to cycle on and off as much as previous heater. digital temp is verified by 3 other thermometers and all are within 2 degrees of each other.

This is my second unit,love the numerical display

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.
