So, as most of you know, I had an awful 3 week ordeal with ich. Finally got it under control (Knock on wood). I was looking at my tetras in the QT tank this morning. They have been in there almost 5 weeks now. Thought we were about ready to move them into the big tank since ich is now gone. Guess what? Yep, 3 of them now have ich! I have to laugh at this point. Heat is up and salt dosed. Nothing was cross contaminated. Even my Python was cleaned every time with bleach and then Prime/water. I went overboard with disinfecting. How 5 weeks later? Oh well, it is what is. Lol!
