my tank is in big trouble

[angelrecruiter]

my corals are dying.. I don't know why every day I look at my tank and there is a new dead coral. I have lost a fish as well a yellow sail tang. all of my soft corals are nearly dead. I thought it was not enough cal and the alk was out too but under my dead corals is a nest and a hole where someone has made a home for them selves.. its been under every coral I have found dead. today I found my open brain and my elegance dead one has a hole the elegance lives on the sand. ive had the elegance for 12 months I bought it sick till I started feeding it amino acids and cal then the colour came back and it was really pretty but the last 3 months its all gone down hill. I have been using straight ocean water as the guy I was buying everything from packed up and left now I have to use the ocean because I have to travel 1 hour to get ro.. I have hitch hikers, bristle worm, snails, family of bandid star fish babys. a worm that is micro and I can see the colour but it does have bands on it. a little pink slug and few other not worth the mention. all my live rock has holes burrows in them maybe I should just get rid of the live rock and swap it with what I have in storage in another container..
can anyone tell me why they are dying I also have fish 2 adult clowns and a large Anemone and a Goby

I have photos if I can find out how to post them..

Get a photobucket account. Upload the pictures to that and use the links from there.

What are your water parameters, temperature, and flow?

I wouldn't necessarily be concerned about critters living under corals- they make good safe hiding places for pods and shrimp.
