Skimmer Mod Question

Has anyone modified a Beckett type skimmer to add a recirculation pump? I havean Marine Technical HSA-1000 and I am thinking about modding it for recirc with a mesh impeller. The skimmer is a bit small for my system, 600+gallons, and I do not have the clearance to go with a big-taller skimmer. Will this help improve efficiency and therefore negate my needing a larger skimmer?

beckett type skimmers use regular paddle impeller driven pumps, usually ones with higher pressure. Running a needlewheel is a different thing all together. The two methods can not be combined.

yep, I understand. I am driving the HSA with an Iwaki 70, BUT, what if I add a recirc pump to the HSA to chop the bubles up even more? A multi pump recirc skimmer is doing just that as well... chopping up chopped up bubbles... right?

Okay, you could do that, but why? Why wouldnt you just use a needlewheel then and not the HSA/beckett/iwaki? If its a height thing, you could always force feed the pump with a linear air pump.

On a side note, needlewheels dont recirculate air for mixing, just water (and then the air is sucked in at the venturi and mixed, etc). Having a needlewheel pump that recirculates air as well as water would lower the skimmers overall air intake, as part of the pumps capacity would be wasted on air passing through again, taking away from its total potential.
