I have been researching the epsome salt bath but I can’t find out how often to give him a bath. I just did a bath with 1tablespoon per gal for 15 min. Moved him to another bath with 1/4 tablespoon per gal for 5 min then back in his tank. There is not much change this quick But how often do I give the bath. Pleco’s and salts don’t mix very well. Anybody have any advice?
