Hi all, I have a 5x2x2 with a small Giant Gourami, a Senegal Bichir and 2 Uaru A's. I am using a cheap 1500lph canister which seems to work well, and a 2500lph internal, which clogs soon after being cleaned. I want to add another canister to the tank. Should I add exactly the same size and type of canister, or should I go for a different brand, or a filter with a larger water turnover rate?
