Kinda freaking out... for some reason my heater won't warm my water about 73... I got an alert from my apex telling me of the drop. The heater is still working because I turn my return off to build up the heat in my sump and it gets up to around 75 and after I turn my return back on, it goes down to around 72 and won't go higher then 73. I have a second temp gauge confirming the temp. All fish and coral still look fine, but I'm sure stuff is going to start getting angry since it's been 24 hours at that low temp.
