Well, I think the maracyn is helping the 38 gallon gourami tank, but the ulcerations are pretty severe. Is there any reason not to put salt in the tank with Maracyn Plus? I have hope for the large tank, but I hate to say that the ten gallon is still under quarantine. At this point this is just infuriating. I've literally tried ten plus medications on this tank (over the course of several months). My water quality is fine, and stepping up to two smaller changes a week doesn't seem to do much.
Unless you've got a better idea, I plan to freeze the overly diseased fish, and quarantine the unaffected ones and they will ultimately end up in my 28 gallon. Then I will strip this aquarium down and start from scratch. I'm just sick of it. No matter how well I take care of the tank, it is diseased. I also have never been able to relieve my algae problem, (though that is much better with the new light fixture) even with only eight hours of light a day and it is heavily planted. I am at my whits end. I have tried sooooo many different things for this tank. It is a money pit and is really annoying me.
