I have a new aquarium and yes I know it's not the ideal conditions.. I have a screen top and on the current 20 Gallon that I have put aluminum foil on the screen part which has really helped humidity and heat wise.. I received a bigger tank it measures 13 inches wide by 36 inches long.. I plan on using flex tape for a under tank heating source and I was just wondering if anyone thought or has an opinion on putting the heat tape over my screen top.. Any opinions are welcome I just wonder if that would help with the heat or be a waste of time.. I realize heat rises but I thought it would be worth a try throwing the idea out..
