Hey folks, my tank is plumbed with bulkheads for my canister filter and I'm wondering if I need additional aeration since the outflow is about 5" below the water line. The outflow is pointed towards the surface, but I'm not sure how much agitation/flow would be sufficient for proper aeration. I've got an airstone in the tank to help with this, but I'd rather go without it.
