Hypo-salintiy in a reef tank?

[curtisvill]

I have a purple psuedochromis which as ich. He is in my 180. I can not catch him and tearing down the tank is a very daunting task for this little fish. I was at an lfs today and the owner mentioned hypo-salinity. He said I could lower the salinty to 1.016 and everything would be OK. This was the first time I had heard this so I am a bit skeptical. Has anyone ever heard of or tried this before? I have a lot of very expensive corals in the tank and I do not want to do anything which would jepordize them. Any help would be greatly appreciated (like how to capture this little guy). Thanks for your help.

SG of 1.016 will not kill ich..1.009 WILL kill ich but it will also kill your corals

Thank you. That was what I thought but I just wanted to be sure.
