This morning I found that my largest tank bred moon (Think) has everted entirely. It turns out that the salinity got too high. Normally the sump drains and the pump stops before the salinity gets to high. In this case, I accidentally left the sump raised at an angle, so the pump had far more water. I added reverse osmosis water to bring the salinity down. Think is still everted, but I have managed to get him to almost revert back to normal.
