I'm very be to fish. I got a small 30litre tank for my daughter and since living it so much i now have a 150 litre Corner tank. I have a canister filter boyu fef 280 which came worth my tank. How often do i clean the media in these? I did clean (in tank water from watter change) the media. I have top pump water back in to the canister after and add i was doing this all bits pumped back into my tank. Why is this? What am i doing wrong? Any help advise would be appreciated
