So confused..ich or not??? Help

[Coralgurl]

I realize this leaves the ich in the tank. I've already said why I close this method, I feel it's the best choice right now. The fish are already sick, stressing them more is not going to help right now.

To top it off, my nem has decided to relocate, all power heads are covered but this is restricting water flow. Anyone has a suggestion on a good netting product? Tried a fish net and now have nylons covering them.
