Hi all, I need some help please with my tank situation. A couple of days ago I lost my coral beauty. I thought it was old age, as I had her over 2 years and there were no marks on the body. It was looking and eating great until found dead early in the morning. Then yesterday the blue damsel (yellow tail) started hiding in the rocks and when came out in late afternoon was all powdery looking. And there I a bad looking path near its top, please see the picture linked below: IMG_1219.jpg Photo by nurka_a | Photobucket Now the outer edge of one of clown fish's fins and tail looks rough and powdery. The most recent addition was a set of corals, one of which didn't open up as fast as others. I didn't dip the coral, very bad I know. I dipped the bad looking one after the fact. And now I'm very worried. Checked the water after the Coral Beauty passed, Nitrates = 0, CA = 500 (my tank's norm), Alk around 6 (dosing it daily, it's been dropping a lot since the addition of acropora), Mag 1300. I'll retest the water and update later. Any ideas on what this could be? Is it Ich? I never had to deal with that so no idea what it looks like. Couldn't find good pictures on the internet either. I did notice some tiny oval brownish looking specs (1/2 mm) on the glass that sort of move around the glass. Any help is appreciated. Thanks.
