need some help My wife was at our local LFS and saw a sea apple. and I dont know a thing about them. our tank is 180 gal with about 200lbs of live rock with assorted soft corals and 7 small fish. water is good nitrates 0 nitrites 0 Amonia 0 calcium is 420 Ph is 8.3 temp is warm though at 81 most of the time. I think that is becouse of all the power heads and pumps. My question is can we keep a sea apple and will every thing else in the tank be ok.
