Aquarium Advice Addict
This is weird, but true. I have three tanks. A 10 gallon, 20 gallon and 55 gallon. I use Aqueon heaters and have absolutely no problem with the 10 gallon and 55 gallon. I set the heater, tweak it until it gets the water temp I want, and that's it. I don't need to fool with it again. But on the 20 gallon, for some reason, heaters don't work right.
I posted about it either on here or another board a couple of years ago, that the heater would get down to 73-74 at night, but at the same setting, it would go up to 80 by mid-afternoon! It gets 10 degrees colder in the house at night, but even so, the other tanks are not affected by it. Some people suggested I not risk it, and replace the heater, so I did. And guess what? Same exact problem with this one! I'm especially concerned because I have Hasbrosus cories in the 20 gallon, and they shouldn't go above 78. Also I don't like it fluctuating 6-7 degrees because I know it's not good for the fish.
The heater is, by the way, a 100 wt. Anyone else have this trouble?
