Marine Ich help please

[dsaundry]

Yes I have cleaner shrimp, as for fish remaining 2 still look suspect, Niger Trigger and Copper Band, the 3 chromis are doing great, I small black angel appears ok, 2 wrasses seem ok and 1 gs maroon seems ok, lost one more clown earlier this am., Nitrates are a bit high as there are some corpses I havent been able to account for. Did a partial water change again yesterday, nitrates are reading about 30ppm. I think all I can really do right now is water changes and montor water conditions and feed. I cannot tear down this tank to try to catch remaining fish. I suppose if I want to sacrifice inverts I could treat with copper but that really isn't an option for me at this point. Thanks for all the suggestions and support from everybody.

Oh and the fatality count is 10 if I have counted correctly
