Yes I acclimate all my corals. Like I said, I dont have any trouble with any other corals. Even gorgonian's and sea fans(which are sopose to be hard to keep). Its only toadstools. I started running a seperate carbon canister on the tank. Im going to let it run for another week and try one more toadstool. If that doesnt work, Ill just wait till the frag toadstools I have in the tank get large enough to put them were I want one..
