Help...fish great but corals are dying!

[exposit]

I have had my 55 gallon reef tank up an running for about 10 months now and haven't added anything over the past two months. It was complete with corals (which are now dying) and 5 small fish (2 scooter blennies, 1 blue tang, 1 dottyback, and 1 clown fish). The first coral I lost was a very healthy leather, then a torch, and now a plate coral. The sypmtoms are simply a very FAST growing mucousy slim that quickly engulfs the entire coral. I do need some advice! My water perimeters are very low levels of ammonia (.05), ph (8.2), alk (1.1), cal (400), sg (1.024), and temp (77 to 81 during a normal day). Help!
Thanks, Christian

Christian: I'm going to move your post over to the reef forum where I think your problem will get more attention.
This forum is pretty much for fish disease.
See you over there...
