I have set up a tank, for my daughter and now i have ick on my two guarmies, and have lost five neon tetras. I have been using the "ick guard" treatment, and nothing is improving. I took some water to the pet store to have it tested, and they said my water was fine. I have gone through 1 and a half bottles of ick treatment, and all that has happened is things are getting worse. I dont know what else to try. Any help? I am very new to this and don't know what to do.
