Ok so I'm going to treating my tank for ich. I have a penguin 350 hob filter. It says to take out my carbon while treating but I don't want to lose the BB on my filter media! How can I keep it alive while it's not in the filter? Can I just keep it in the water for the few days that I'm treating? Will it be fine or should I run an air stone in a bucket with it? Any advise would be appreciated
