I concur on a canister, and definitely keep the ac110. On a 6 foot tank you need intakes on both sides of the tank regardless of the filter size.

They are plenty large enough to support the bio load of africans and remember, they're rated at 500gph x's is 1000gph= 8x's per hour that tank is getting turned. Topped with regular water changes, you'll be completely fine.
