Like everyone has said, raise the heat slowly until it is over 82F, and just keep monitoring them and the other fish, but also do lots of water changes and clean out the substrate when you do the
water change, it will help with getting rid of the ich.

If you don't have any inverts in your tank, ones that you like, you could always get a 2" piece of copper pipe from the store, clean it really well, and add it to your filter, from experience, it works really well and I haven't had to raise the temperature in the tank for a long time and I also haven't seen any unwanted snails in the tank either. I found this out when my 36 had a really bad case of ich and I lost 90% of my tank. I was at a point of not really caring if it worked or not cause I tried everything else, so to my surprise, it worked really well and the fish have been fine and doing even better then before.

to Fish Lore. So hate to hear that you're having ICH issues. Raise your temperature to 84 or 85 degrees. The salt is "not" necessary and I don't know how well the Clowns will react to salt! Leave your temperature there for 2 weeks. Add an air supply line and stone if you don't have one in there already. Warmer water needs more air. Vacuum twice each week to remove the spores that fall off the fish and into the substrate. ICH cannot survive or reproduce in temperatures over 82 degrees.
