Thanks!If it is epistylis this is how i treated it, others may treat it different also when i treated my fish weren't as far as long as yours.
but yes i would add 1 tble spoon of salt per 5 gallons then every other day i would do a 80% WC with a very through vacuum making sure to vacuum the sand or gravel what ever you got when the epistylis falls off that's why you vacuum and redose with the salt.
It will actually clear off the fish in about 2-3 weeks but i keep doing it for a month to make sure its gone out of the water column and not in your sand or gravel
As far as regular water changes go, let’s say without any sick fish, should I be adding salt or anything else to the tank other than conditioner? I realize this is a whole other debate and there are a lot of different opinions. As far as salt though, should I add after each regular wc? Not just when treating sick fish but every wc
