So ihave a 30 gallon and have two goldfish. They are going to go into a pond soon but a while back they got ick and what not. I also had a pleco with them.the pleco ended up dieing and decided that I would cure the tank with 1 tablespoon of salt per 5 gallon.do you think its okay to put one in despite it having salt? I have done a few water changes since then
