We bought a beautiful pink plate coral (about 3" diameter) from the LFS about 3 weeks ago, which had a very small white patch in the center. Slowly, brown algae has grown in that region (at least, I assume it's algae), exuding bubbles of ?air or ?mucous that sit suspended right over it. The same sort of algae, minus the bubbles is also growing all over the underside. Several times, I've scraped away at the algae (with a plastic, nonserrated knife), figuring I would impede its growth and allow the coral to "outgrow" it, but it hasn't made a dent.
What did we do wrong, and is there any way to save it?
BTW, we have MH lighting (2 x 175 W for a 46 gal tank) and 2 MaxiJet1200 PHs in the tank. This is our only SPS coral, but we have a variety of leathers and a frogspawn in the tank, all of which are doing well.
