I just got back from a weeks vacation. My wife had a horrible time taking care of the tank. The sump kept over flowing on here (because I set the auto topoff to dose way too much daily) and as a result she had to remove water. All the corals look good except for a small green digitata I had that is all white now. But yesterday while on my way home, my BTA took a trip into a powerhead. It doesn't look dead, although VERY damaged. My wife scooped up all the little bits with a net (the ones my zoos and palythoas didn't eat). This morning the BTA has opened up some and my clowns look like they are trying to cheer it up. I don't know if I should leave it in or pull it out.
