is a 50 watt heater enough for a 20 gal non planted tank?
I wouldn't think so. Its usually 4-5WPG on heaters, so i would go for a 100W in a 20g...
yea thats what i thought i just upgraded my 10 gal to a 20 and was hoping the heater wouldnt need an upgrade too but no big deal ill upgrade and continue cycling. thanks
