Good morning all. My current pre set heater gives me a constant 76 degree temp. I have confirmed this with an old school in tank thermometer and ink bird temp controller. It never gets above 76.3 and never below 76. I’ve monitored the heater and really doesn’t come on that often to maintain this temp. Will 76 be ok for a mixed reef with fish or should I look to get a better heater. The current chart shows my daily trend and it doesn’t deviate from this ever.
