Does any one use Aqua Lifter for dosing pump? Especially Calcium reactor pump? I'm having trouble setting it up properly, even when the power is cut off, the pump is still running and further pumping water through. Mine is plugged to an Apex EB8 and it continued to running even when the outlet is shut off. I also tried unplugging the pump, then water continue to pump through as if there's a vacuum. Any advice would be greatly appreciated.
