This tank is about an 8 gallon tank, at least that how much water I put in it

anyway, I think I may need a filter that is easier to clean or requires cleaning elss often

the filter I have not in a Duetto Internal Power Filter, it has a mechanical filter, a bio filter and a carbon filter. The problem is that with the addition of my common pleco the filter gets clogged rather quickly with pleco poop and other things.
What would you guys suggest as filtration for this tank? It currently houses a Batrochoglanis raninus or Bumblebee Jelly Catfish and a common pleco from Petco.
they will both be moving to another tank soon, much larger, at least 55 gallon or bigger. as for now they are well fed and happy

I can actually get the bumblebee out during the day! he refused to do this for the first month or so I had him (rescued him rather). I beleive he may actually recognise me now as the food bringer, everytime I come by the tank he pokes his head out and points both his Barbels out at me, the same he does for food. Kinda like a puppy dog waiting for a treat.
