Columnaris And Filters

[LDan]

Does columnaris inhabit sponge filters and filter media? Say I take them out to treat the tank with furan 2 and kanaplex, can I put them back afterwards or will they re-infect the tank?

Columnaris is a natural bacteria present in all aquarium environments. The bacteria grows exponentially when it takes hold inside a stressed fish. The longer the fish incubates the bacteria the more virulent it gets. Without a host fish the Columnaris dwindles.
I don't believe the filter media will cause another outbreak.
After the outbreak is under control, make large 50% WC's each week for approx. a month then slowly begin adding new stock.
