if you just got the filter a week ago then your tank is in the cycle mode because the filter has not had enough time to devolope the beneficial bacteria it needs to fight the fish waste being produced. Do you have a filter on their that is already established? if not your situation may get worse. This is why in the future if you are going to add a filter and are going to remove the old one wait until your new filter is established before removing the old filter.animal planet;1543146; said:
