  • Reliable, Accurate, and Affordable
Size: 200W (for 45-80 gallon)
I've got the AQQA 300W heater on my 55-gallon planted tank for about a month now, and I am thoroughly impressed. I was a little skeptical because of the low cost, but this unit works! Setup was a breeze — the suction cups are solid, and the screen is clear and bright (even from across the room). I put it on 77°F and it's been rock-solid ever since. The digital control is very user-friendly, and I like that it has a built in themometer. You can actually see when it's heating and when it's idle. My fish and plants seem happier with the stable temperature, and I’ve noticed less condensation and glass fog near the heater, too. It’s also very quiet — absolutely no humming or clicking like some other brands I’ve used. All in all, I’d say this heater performs just as well as others I’ve used that cost twice as much like fluval. Edit - I had to return this one because I found another heater that fits in my canister filter. But it doesn't change the fact that this was a great heater. ... show more

  • Solution Error fix! Solution Error fix!
Size: 200W (for 45-80 gallon)
I see complaints about people that owned this for a year and they start getting error messages after the warranty expired. The same thing happened to me, but first I saw the heater was active way more than it should be (for a while) the difference is I know how (I think) to fix it. FIX FOR THE ERROR MESSAGE if you look at the heater it builds calcium up just like any other heater so you have to clean it. I would not buy any dealer solution for it as you FISH LIVE IN THIS WATER so I use vinegar and water. I took a pic of it soaking and as bad as it is it's going to take a few days so I recommend getting a secondary heater while this happens. Unfortunately don't have one so I came back to order a 2nd one and hope my fish will be ok. I'll update this if it doesn't work but if I don't then it did ... show more

  • Good heater
Size: 200W (for 45-80 gallon)
I have 5 of these in freshwater tanks ranging from 30-75 gallon, some running over 2 years, no problems. Easy read led temp display, easy adjust. I do recommend this heater

  • Great heater with no hassles
Size: 200W (for 45-80 gallon)
I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. While much larger than most of the other heaters they work great and when mounted horizontal at the bottom of the tank you dont notice them that much. The fact that it remembers the temperature you set it to even when the power fails is a great feature. Keeps the temperature within 1 degree of what you set it to at all times. The easy to read display and being able to see the temperature you have it set to and what its actually at temp wise is awesome. ... show more

  • Great Quality!

Great heaters; only one out of six was off by 6 degrees. But still worked great.

  • Convenient controls, nice looking
Size: 200W (for 45-80 gallon)
I love that you can make adjustments outside the aquarium. The last one we had was submerged so it made it difficult to change. Although we didn’t have to adjust the temperature often, it is nice to have the control on the outside. So far it is working as it should. It’s definitely an upgrade from what we had. ... show more

  • Easy to use and you can set it and forget it.
Size: 200W (for 45-80 gallon)
Had 2 for slightly over a year, never had issues and worked perfectly. I set them and forgot them. I am buying another one today as one is beeping EE error. Too bad it is only a month after the warranty, but it is no fault in design. I set it and forgot it to the point that a lot of algae grew around it and I left it cause it looked good. I wont do that again, but since it worked perfectly under those conditions for a a solid 6 months, I trust this heater. ... show more

  • worked great for 2 weeks then catastrophically failed in a very bad way
Size: 200W (for 45-80 gallon)
I bought the 200 watt version of this heater for my 29 gallon aquarium and it malfunctioned after 2 weeks. Came home to find that the water looked cloudy. The display indicated that the unit was set to heat the water to 81f and that the temperature of the water was 78f. Put my hand in the water, clearly not 78f. I temped the water with a digital thermometer that I know to be 100% accurate and found the water to be at 95f. I was expecting this heater to be reliable because of its digital controls and its advertising that boasted about its accuracy and reliability because of its its dual temperature probes. It specifically mentioned that if a temperature probe failed it would not keep heating up the water --- “If one of the probes is broken, the entire heating rod will stop working. There is a double insurance to prevent the probe from being broken and the heating rod will continue to heat up”---. I should also point out that the advertising of this heater indicates that it has an over temperature alarm which never went off on my unit because the electronics on this thing couldn’t even tell that the water was hotter than 78f. The heating element was basically on 24/7 because the heater thought the water was at 78f when in reality it had already heated the water up into the 90’s. I recommend that nobody buy a heater over 100 watts unless it is really required for your setup to reach the temperature you want. That way if it fails there is less of a chance of it heating up your aquarium to unsafe temperature levels. ... show more
