Look, Ive been there. Youre standing in the middle of the pet store. Youre staring at a wall of boxes that all see exactly the same. One says 50 watts. another says 300 watts. You begin con mental math that would make a calculus professor sweat. You just desire to know one thing. What Heater Size Is Best For My Tanks Volume? It shouldnt be this hard. But honestly, the "rules" they print upon the put up to of those boxes are often warm garbage. I scholarly this the difficult artifice help in 2016. I bought a heater that was "rated" for my 55-gallon tank. Two weeks later, my tropical fish were basically thriving in a slushie because my active room was drafty.
Picking the right aquarium glass calculator heater wattage isnt just very nearly the size of the glass box. Its roughly the environment. Its approximately science.

Weve all heard it. The golden rule. Five watts per gallon. If you have a 20-gallon tank, get a 100-watt heater. Easy, right? Well, sort of. This is a decent baseline for a room that stays a consistent 70 degrees Fahrenheit. But who lives in a absolute room? My apartment is basically a wind tunnel in November.
If your home is chilly, that 100-watt heater is going to be doling out 24/7.
