Also, make sure you vaccum the bottom of your tank very well with each water change to try and remove any fallen ich cysts that came off the fish...
Otherwise this may end up as a never ending battle...
Yea for sure I've been vacuuming it out almost every time. Was actually thinking about switching the substarate to black sand instead so i was thinking about taking it out and going bare bottom till they got better. What do you think?
