I have just built a 48x42 220 gallon tank now i need to filter it. I was wondering if 2 ac 110 would be good enough for a heavily stocked african tank ?
Two Aquaclear 110s would be rated for 220 gallons combined. I've never known any manufacturer to rate their filters for a heavily stocked tank. They usually overestimate the size of aquarium they can filter. I don't think 2 aquaclear 110s would come close to filtering a heavily stocked african cichlid tank. I'd suggest 2 fx5s or a good sump and an fx5.
