I have Ich, any suggestions

[danny zubot]

It's Hyposalinty. The low down is that inverts including the Ick parasite can not live velow a certain salinty level. By slowly decreasing salinty of the water your fish are in, you will eventually kill the parasite. Fish won't be effected as much, and in most cases will actually benifit from a brief period under lower salinity levels. This is because lower salinity decreases a fish's osmotic response and makes it easier to breath. (A good idea because they're usually stressed a bit from the ick)

Once the ick is gone you raise the levels back up to par, but slowly. The whole process should take 6 weeks. It can be done faster but you need to leave the leave the main tank fallow for 6 weeks any way to allow the parasites to run their life cycle.

IMO Ick additives do not work, I've tried them. Do whats best for the fish and go hyposalinty. If you google Hyposalinty treatment you should find the exact procedure which will include how fast and how long to drop your salinity.

Thanks,
