help, suction leak!! (fixed with new pump lid o-ring)

Other considerations, any leaks after the pump are pressurized and should appear as water squirting out, not drawing in air. The only exception is if there is some sort of venturi action, such as with spa jets.
Another possibility is cavitation in the pump. Make sure you're not starving the pump or dead heading it. Cavitation will sound like popping sounds or gurgling noises in the pump.
Pump starvation will appear as a lack of water filling the pump trap. This can be caused by an incorrectly positioned valve before the pump or debris in the skimmer basket or plugging the suction lines.
Dead heading the pump is when a ball valve or diverter valve is blocked off or reducing flow after the pump, and not allow the water to flow back to the pool properly.

Alot of times, you cannot see smaller bubbles sucking into the pump trap area. At the same time, these small bubbles can be more apparent when they come out of the return jets.

I believe you mentioned that the salt system was not generating due to the low salt reading. Therefore, it probably is not as a result of the salt system.

Thanks guys, although I had already inspected and flipped over the gasket on the pump input canister lid, today I replaced it with a new one. The bubbles continued for a few minutes, then stopped. I guess some air had built up inside and it took a few for it to get out. BTW, had to order new cell for aquarite. Found it for 379.00 on the web. Pool store quoted me 815.00. I only paid 795.00 on the web for the whole system 6 years ago.
