another change of plans for pumps.
Waveline DC 12000 brushless variable speed aquarium pump.
Talked to the guy at RLSS and the new DC6000/12000 come out in March. They are controlled by the APEX through the standard 0-10v controller output used for other pumps and LED dimming. definitely going with a pair of DC12000 now. These pumps have been shown to flow 1,000+gph on only 40-50 watts
