Have you done water changes, get new lights, and get rid of the yellow tang yet? Also, what do you have for clean up crew, and are you running carbon/ gfo at all?
I have not done a water change yet. and by new lights you mean bulbs?? and yes i actually got rid of the fish my cousin had and started over. i just bought about 30 blue legged crabs and about 6 snails. i do run the oceanic biocue fliter pads that have carbon in it. I probably sound dumb but whats "gfo" haha
