Wonder if anyone has any ideas. All that i can find is problems with airlocks, which I have had in the past. Today though, my pump doesnt even make a sound. The batterys fully charged, but when I turn it on, the lights come on, the green and red, not the blue, so i take it its not dead ending, but the pump wont make a sound. This is a first for me. Anyone else may've had this problem, would be great to know how you solved it,
many thanks
