Your inverts should tolerate teh salt treatment, although you may see some snail inactivity. If at all possible, remove any applesnails prior to treatment. You build up the dose over a couple of days. Table or aquarium salt is fine, table salt is much cheaper. With the salt treatment, you can do water changes you just redose the salt for the volume of water exchanged, being sure to dissolve it in tank water first. Doing deep gravel vacs and wiping down the inside of the glass is a good idea. Hopet his helps
Thanks for the information, it helps a ton. Good thing I've got another tank that's not contaminated for my new cherry shrimp and snails (hope they get here today!!).

Ich guard works great. But it will turn your decorations blue, and kill your snails. So I would move the shark into a smaller tank (if you have one) and treat it there.
Thing is, there's 5 sharks, and they're all over 6" long lol. I just picked up a 90gal tank, but I have nowhere for it to be setup at the moment, and of course it's nowhere near cycled. I guess I could use one of my established Rena filters on it, and use water out of the 300gal to jump start things...but that also doesn't fix my main tank, nor the issue of where to put it even temporarily. More fish than just the sharks have the ich now =/.
I think salt is the way I'm going to have to go =/. Just hope my plants live through it.
