I had a leak in my sump and my Bubble Magus curve 9 was running without water. The motor is turning the impeller but not strong enough to create bubble to fill the skimmer. I took the impeller out and cleaned it, but still nothing. I am running it in fresh water and vinegar to make sure it is really clean. Am i wasting my time and require a new sp4000 pump or perhaps just the impeller part?
