When you treat your tank what happens to the parasites? They get pooed out and disintegrate and die? Do their remains lay in the filter media? Do I need to do a 100% water change and rinse media? Just curious as I treated my 150 gallon which only houses two baby bonsai flowerhorn for internal parasites they had when they arrived in the mail. One is no longer popping white but the other still seems to be. Anyway just curious as to what happens to the parasites?
