My new 90 gal finished cycling about a week ago and I did a big water change just after. My params look good. My question is how long should I wait until I start adding sps corals and clams. I have a full clean up crew already. The tank is going to be strictly sps and clams but should I add something like ricordia mushrooms to see how they do or just start with a small frag. I would appreciate any suggestions.
