So i was having a major dino problem a while back and was told to take off all my filters but my sump bc inless changed every week or so the nitrates would build up in the filter fabric and cause a problem. So I removed both my hang on filters and my Magnum 360 canister filter. My Question is can I use the canister filter for anything good in my tank like carbon or phosphate remover or something. I paid alot of money for it just to sit around not being used lol.
