hello, I have just taken over a tropical fish tank, I have 1 pleco and several platties,and a lot of fry, I have had a problem with white spot that seems to have been resolved now I hope, I was just curious as to how long white spot takes to totally clear away as I would like to get more fish for the tank, as I said earlier I am very new to all this and would be grateful for any help and advice on this please thank you
