The best filter for pleco tank

[Barry Tetra]

Hello, my 55 gallons tank have 3 common pleco, 1 L001 pleco, 2 black ghost knifefish ,chinese algae eater, 2 burmese border loach , 1 clown knifefish and clown loach
What filter should i use? Even the power filter cant handle that much poop in the tank.
NO Substrate

No filter will help you out of this, because you have too many large fish (and an inappropriate mix) in this small tank--a 55g at 4 feet/120 cm presumably is far too small for the common pleco (even just one), both knifefish species, and the clown loach. And having no substrate is making the water quality much worse; the substrate is the primary source of the necessary bacteria in any aquarium.

I've gotta agree.

With this stocking you're water quality will suffer and the fish won't have enough room.
