A while back I started using the natural stuff rid fungus for some fungus my
betta had. I stopped using it about 2 weeks ago now my problem is the brown stuff (looks just like the rid fungus stuff) is taking over my tank. It's on the plants the cave the glass on my tank. I remove it when cleaning the tank as best i could. It just wipes off easily but comes right back. I rinse the filter off good in used tank water. so i don't know what to do about it. I was thinking of putting some new filter floss in there together with the current filter to seed it then get rid of the old stuff thinking it has to much of the rid fungus on it.
What do you guys suggest?
