I am sorry to report that I downgraded my tank. I am not sure why my tank crashed, I am thinking something to do with the flatworm outbreak, or my weak lights, but most of my corals have died. I have placed a few surviving colonies into Dan’s 75 gallon, in hopes of keeping them alive. After taking out all the live corals, I have also removed the lights and the powerhead. I have a filter and a heater running. My two fish are still in there.
