keeps new fish eggs more effectively free of fungus
Didnt resolve my aquarium fungus but I think it was the wrong diagnosis, I tried it to keep new fish eggs free of fungus and it seems much more effective than Methylene Blue

seemed to work
Killed the living fungus quite well but once I started phasing out it slowly started growing back… not sure if this can’t kill the spores or if something else is responsible so I won’t dock stars from it but you decide if you want it. I will say once it went in the water the fish recovered quickly! Also a downside, it is bright green and the directions for removing the green involve activated carbon filters which many new aquariums don’t use so removing the green is a difficult and lengthy process.
