Ich Problem Please help

[dragonmoray]

Hi everyone.
I recently introduced a new fish into my tank (blue stripe angel) without quarantining it first. I was told by a few reputable stores that it's not a good idea to move this kind of fish around. I should have quarantined, but i didn't.
Anyway, I noticed some small white spots on the fish two days after putting him in the tank. The next day, the white spots where no longer there. A couple days went by without any noticeable problematic signs, but now all of my fish have ich.
I do have a 65-gallon hospital tank, but my main tank is 400 gallons. There is no way that the hospital tank can support 14 fish.
I have the following fish:
Japanese Dragon Moray
Snowflake Moray
5 yellow tangs
Blonde Naso Tang
Sohal Tang
Harlequin tusk
Clown Trigger
Crosshatch Trigger
Blue Stripe Angel
Emperor Angel
The main tank has 300+ pounds of live rock and crushed coral for the substrate. I know hypo-salinity would probably be a good thing to do, but I don't want to kill the live rock.
I would greatly appreciate any suggestions/advice.
Thanks much

Dragon, I'm sorry that you got such poor advise from the LFS. Now you have big problem on your hands.
You have no choice but to hospitalize all the fish and perform hyposalinity. You should contact the LFS that gave you such BAD advise, and suggest to them they are partially responsible for this disaster. Ask them to let you borrow one of their old tanks to set up another hospital so that you treat your fish.
You absolutely CANNOT do an effective treatment within your main tank. Don't be talked in to making another mistake by adding one of the "so called" reef safe ick treatments to your tank.
