i have recently found out that if i keep my heater off my temp in my tank will stay at 76.1 with zero fluctuation throughout the day. Is this too cold for sps? I used to keep the tank closer to 80 but it would go up and down a degree or two throughout the day and i was always afraid of the dreaded heater malfunction? right now the corals look happy but didn't know about long term affects?
