Hello everyone,

I got a bacterial infection in my grow out tank (150% daily water changes)

It all started in the fins being eaten away starting from the middle not the tips, then it seeps towards the flesh. it showed on 5 fish, so i sedated them and cut the soft rays. and dosed 5ppm Enrofloxacin daily after 100% water changes.

Now even with the presence of the antibiotic something new appeared and it grows on any surface on the tank slimy fluffy whitish stuff as in pic below. what is this stuff?

It took over the filter media and the power head i was using to do auto water changes, I placed them in a bleach solution.



Now since I don't have bio filtration i cut feeding to once a day with 100% WC
