Last saturday I changed from gravel to pfs in my tank. Ever since monday my gt has had a cloudy eye. I took my water to lfs to get tested they said my water was fine. I have started treating with melafix, per there suggestion. I do 30% water changes every saturday. I am just looking for any suggestions on how to treat this. Or possibly reasurance that im doing the correct thing. I never have gotten anything but the ich in any of my tanks for years. So this was new to me. Thanks for your time.
