A week ago this past weekend, my 125 gal reef tank was doing great. Chemistry, corals and fish all looking wonderful. Monday, I got home from work and all the coral are closed up, the skimmer is going crazy, and there is foam in the sump as well. The fish did not seem bothered. I did an emergency water change of 30 gal Monday and Tuesday night. After the second water change, I checked the chemistry and the only things off were the PO4 at 0.20 and the magnesium at 1125 ppm. I changed the PO$ media and started correcting the Mg++.
It wasn't until a few days later that I noticed that all the Caulerpa in the sump was "gone". Not dead, but gone- likely disintegrated. But, Im not sure if this is cause or effect? I have never had my Caulerpa die like this. I keep it illuminated 24/7.
A week + later, my T. derasea has died, the soft corals are still withdrawn and/or closed, my chalice, Favia, and brain corals are fine, and the fish are fine.
any thoughts?
