You can buy Red Sea filter cups and put pollyfill in it it is way easier to clean than filter socks it takes less than a minute also if you have nylon media bags put carbon in it put it in the bottom of the cup and your pollyfill on top my then goes over a 8 inch acrylic wall which then is filtered by 2 35 ppi sponges and 2 50 ppi sponges into 2 return pumps with heater and there is room for protein skimmer if I want to go to a reef tank in future
I'm considering turning my 150 gallon (which currently has two canister filters on it) into a sump system. Any videos on making this sort of conversion? I'm reluctant to drain and attempt to drill the tank with bulk heads.
