Ok, so I have the Marineland Penguin 100 filter that has a mini-bio wheel. I just changed the filter cartridge yesterday. I have the old cartridge in a stocking hanging in the tank on the side. I wasn't sure if the biowheel had enough bacteria to compensate for the filter change, and was worried that a mini-cycle would occur without the old cartridge. Just wondering how long I should leave it in there, thanks.
