Thankfully everything in my tank is a frag. I just started with the coral aspect like 3 months ago and started dosing with seachem calcium and alkalinity. I also have a couple bags of aquapure elite in my refugium. I have some mushroom, 3 frogspawns, 1 green trumpet coral, that yellow thing, and some zoanthids. Its all in a 93 gallon cube. With a few small fish in it. I have a small light on it but I plan to buy a bigger one in a couple months (right now everything is under the light), once I buy the new light I can expand the area where the coral lays so they are not so close to each other. I've had that rock with the yellow less then a week. It was given to me. It seems to be doing good under the light but it some of the yellow had some brown on it as if it didn't have enough light. I was told that it was at the bottom of the tank it came from. I put it under the light hoping that it would have less brown. As far as fragging goes I'm hoping i'm just going to have to pop some mushroom off of some rock and relocate it.
