I have a 75 gallon and 20 l sump. My question is what size heater if any would I need for a reef environment. My temp seems to stay 78-81F. Obviously winter I realize I'd need one. But house is constant night78 day 80-81. Tank is topless for now. I'm not sure if I really need one ATM with no corals and future live rock curing then fish. Corals will be introduced shortly thereafter. Not sure on what types though. And if anyone has specific advice on a reliable automated settable heater I'm game for the suggestions. Thanks in advance
