Prism Skimmer Problems

[robbyville]

I'm not sure if it's the same pump but is this a Prism Pro? If so, I also had a problem with the pump, especially noise factor.

When I dissassembled it and watched it run I found that the impellor was struggling and actually not spinning but rotating back and forth. This did not cause any micro bubble problems at all, the pump would simply not draw any water. The problem did start similarly to yours however.

I ended up replacing the pump through the company n/c. The pump was roughly the same age as yours when the problem started.

It may be worth dissaseembling and running the pump so that you can look inside and make sure it's running properly.

Best,

Rob
