Hi! I need some help getting columnaris out of my tank. This started around a month ago when I got some new platies and they were unfortunately already infected with columnaris. It spread to the rest of my platies and I treated twice with Furan 2 and Kanaplex, but sadly it didn't help. Now all I have left is my betta who somehow managed to avoid being infected. Even though the hosts are gone the bacteria has stuck around in my tank. It sticks to the glass, the substrate, my filter, and the driftwood I have in my tank. I recently took everything out except my filter media and cleaned with hydrogen peroxide. This helped a little bit but it is still present. Any tips on how I can get rid of it for good?
