The Constant Q Pond Outlet (CQ) is a unique and cost effective skimmer used to improve the quality of water discharging from ponds by drawing only from the upper levels so that only the clearest water is discharged. The CQ is a constant discharge device with a fixed orifice depth that allows for a much shallower float body than the Reverse Q (which see), and better suited for the shallowest of ponds.
