Ok. So another idiot absent minded mistake. I put my powerhead on feed mode (MP10) and unplug my returns when feeding (can’t wait for sump and automation). I did this yesterday after work. 7pm. As usually after I unplug I take my dog for a walk. Giving ample feed time.
I realized I did not reconnect(plug in) until tonight. 7pm. When I saw my tank didn’t look happy. Fish moving very slow. Some corals acting odd.
Tank was 72 degrees. Luckily no losses. Everything bouncing back rapidly as the warm water cycles in
