Hmmm, that's a fairly tall tank, so adding two extra extensions, as you say, should increase the circulation, but the AC 200 motor and impeller may not be strong enough to draw that deeply. Is the water up to the level of the outflow of your filters? Have you ever noticed, while doing a water change with the filters still running, how the flow decreases the lower the water level gets? Go with the extra extensions, top up your water and see what happens.... Also, sounds like there's lots of stuff floating around in your tank that could clog up any filter. I'm just curious about that...
