Hello, around 3 weeks ago I added some eSHa 2000 to my 230l tank as one of my platys looked to have fin rot. I asked on this forum and they agreed with me. 3 weeks later there is no difference although it also doesn't seem to be any worse. One of my rainbowfish now looks to have a similar problem. Does anybody have any idea what else this could be? I tested the water and it all looked fine.
