All corals closed after addition of zoo frag.

holy cow! 150 polyps? that's why lol. in his little 10 gallon tank that's like stacking a semi on a volkswagon! It can be done, but very carefully, and the volkswagon's gonna get hurt.

I thought he meant it was a little thing, like 5" across or so. I know what kind of rocks you mean now because I was plannong on getting one for my 120 gallon setup and was thinking cautiously about the large biomass addition. I think it was just the fact of adding something so large into his 10 gallon tank. and the 50% water change could have caused problems too if the water parameters weren't EXACTLY correct. I had an 18 gallon nano with 18 gallons sump space and it was VERY finicky for water quality because of the tiny size.

I think it was just WAY too much added at once.
