Hi, this is my first post after doing lots of reading here about chemicals. We bought a house with a pool and have been working on getting it in good condition.

Should I have any concern about bubbles coming out of my return jets when the pump's running? When I look through the clear lid on the pump, there are a few bubbles swirling around in the top of the lid, but not a lot. I have read that the pump ideally shouldn't have any air in it. Is this small enough to not be a concern?

Info:
16x38 concrete pool, built in 1963.
Sta-Rite DuraGlas pump and Sta-Rite Crystal Flow filter.

Thanks!
