I've had my first reef tank (120) 10 months now and am having trouble keeping blue mushrooms. they maintain color but shrink to almost nothing w/in 3-4 weeks
nitrate 0 (I only have 2 fish and have always had 0 nitrates)
i keep them on the bottom in the shade. I have T5 lights white/actinic combo. what's strange is that my hairy mushroom is doing great. it already grew and split.
this is my second try at blue mushrooms. the first time it happened, I thought it might be tank maturity, but I guess not.
other corals are doing good including a variety of leathers, frogspawn, zoanthids, and bubble coral. I have a cuc of hermits and snails. . I do a 10% weekly water changes
I do not supplement feed them. should I? if so, with what?
any suggestions? thank you so much
