I thought so. Something must be wrong with my water. Im using API master test kit. Hasnt expired yet. I didnt rule out on HITT and has been feeding him his food pellets with metro in between kanaplex treatment.Something is wrong with your water. Not only are the holes in the fins getting worse. He now has open HITH sores on his face.
