I've had to start treating my betta for fungus issue. I'm currently at the highest level 1 tbls per 10 gal. Do I need to do water changes while doing this? I am also dosing him with ich x. I'm certain he has water fungus...water mould? which is also known as saprolegnia. It's been a week I just moderately treated him with salt and mostly relying on ich x to heal it but I see no improvement. I did a salt dip once with no result either. So before he goes too much longer I need to upgrade my treatment. I feel I should also add maracyn for possible secondary infection. Any ideas? In particular with the addition of so much salt while dosing with ich x...the question of water changes is confusing me.
