This morning I when I looked at my tank I noticed that my sump level was a bit high which was a little weird because I knew I needed to add some topoff. Looked at my return pump and it wasn't pumping! I have a temp controller in the sump and because water wasn't flowing through it was heating up from the
skimmer pump which in turn, kept the fans blowing on the display. I'm not sure how long the pump hasn't been running but I'd suspect about 2 days. Everything appears to be okay except for my largest
blue tipped acro colony which appears to be losing it's color. Once I took the bad pump out and put a backup in place the temp controller was reading 76!! Is that too cold or borderline?
Also wasn't skimming the water for the same amount of time because there was no flow into the sump.
