My zoos are all closed up and have been for about two weeks. I have done a water change and tested the water. The amonia is a little high but nothing else seems to be bothered. I dont know what to do. HELP?
I tested nitrates, nitrites, amonia, ph, and salt levels. I just did a water change 3 days ago. Could this be a criter or a disease? But would a criter affect all colonies at the same time?
