Thats the problem there are no healthy tanks I know of in my area I DO NOT trust our LFS or any of the chain stores ... I know I have seen ich on at least a few of the fish.
What exactly is your method Wookie? Just put the fish in and let it go? I am just curious.
I will let it go until my test results come out too high ... Then I will change some water.
How High can I let the nitrites get?
