I don't want to buy another heater when I already have one. Problem is it's a cobalt neotherm 300watt heater. I'm getting a 5 gallon tank...is this overkill? My assumption is that it isn't because the heater will only keep the water at the temp I set it to and won't really matter how strong the heater is. Thoughts?
