Hey everyone thanks in advanced my Return Pump in my AIO Keeps Draining my AIO I have Cleaned the pump every time I turn it off with my Apex it fills back up all the chambers and when I turn it on it drains the second chamber and last chamber (the return chamber). I am lost on what to do I have cleaned all the baffles to make sure there is no clogging my aquatop Return pump doesn't have any Adjustment Settings.
