i have a 265gal cichlid tank. i want to make a carbon reactor, can i please have some ideas. what i did so far was bought a cascade canister filter. took everything out. and stuffed it with carbon. it filters from the wet/dry and then back into the wet/dry. then i have another pump to return into the tank from the wet.dry. is what im doing a good way. or is there a better more effective way.
