Pro Heater

I picked up this heater for our 10-gallon tank, and after several days of adjusting it and watching our tank thermometer, I'm happy with it. It attaches easily, the indicator light is great, and fully submerging it hasn't caused any problems.

The only downside is that it consistently runs 2-3 degrees low: I have it set to 80, and it keeps the tank at 77-78. That wasn't hard to figure out, though, and it does hold the water at a steady temperature.

Given the horror stories I've read about other heaters, I'll take one that runs low and steady over one with serious problems any day.

Update: A month later, it's still rock solid, responsive to changes in temperature (like when I add water during a water change), and performing well.

After having an Aqueon 100 watt heater for three years, I noticed that the temperature in my fish tank was not coming down from about 80 degrees even when I set the dial on top to 72. I called Aqueon, and told them that I tested the temperature with two different thermometers (one being digital). I also told them that I never took the heater out of the tank, so it never had a chance to get damaged that way. I also have a UPS on my tank/heater, so if there is a power outage, the heater is protected with a surge protector, and stays on for at least an hour with the battery backup. Here is what I just emailed Rob at Aqueon who didn't want my old heater back, and immediately sent me a replacement "Pro" heater at no charge, even for shipping:

"Hi Rob, I just wanted to let you know that I got the replacement heater, and installed it yesterday. I set it about halfway between 76 and 80, so as to try to achieve a 78 temperature in my 26 gal. tank. I may have been off a bit in my setting on the dial on top of the heater, as this AM when the temperature in my house is 72, my tank is now at 79 (within +/1°). This is a success to me, as my tank never went below 80 to 82 with the previous heater. I have a full glass top and a full wood cover on my tank, and that seems to keep the heat and condensation inside my tank. But, I'm now convinced that my previous Aqueon heater made of glass eventually had a defective thermostat, so I appreciate your good lifetime warranty service that backs up what Aqueon says on its website: "All Aqueon heaters are guaranteed for life."

Very good aquarium heater. Once installed it brought a 55 gallon tank up to temp in a little over 2 hours. Been constant ever since!!

Don't know what to say, it's a great heater! It works great and keeps my tank nice and warm.

If your confused on what wattage to get, use this guide:

20 gal 50 watt

40 gal 100 watt

50 gal 150 watt

65 gal 200 watt

75 gal 250 watt

This is a rough estimate, it depends on how cold your house is which, obviously, effects how cold your water is. For example for a 55 gallon tank I got a 200 watt heater to be on the safe side.

Hope this helps! :-)

I've had several heaters in the past. Most of them had a sliding scale of Hot and Hotter. This one has a temperature gauge with ACTUAL NUMBERS on it. Not only that, they work too! I'm so pleased with this heater. It's awesome, and way better than the others I've had in the past. It looks better too.
