I just purchased an Aquaclear 20 to use as a filter for a 10 gallon quarantine tank. My plan was to attach this filter to my 55 gallon tank for a few weeks in order to cycle it before setting up the quarantine tank but this filter is not fitting on the rim of my tank. I managed to squeeze the filter sponge from the Aquaclear into the filter I am using on the tank, an Emperor 400, and placed the mesh bag with the biomax inserts in a back corner of the tank. This should be enough to seed those with the bacteria I need, right? Also, how long long should I wait till I pull them out and set up my quarantine tank with them?
