Hayward SP problems...new to pools..

[JKashJ]

I'm in Georgia, so we do have freezing temperatures, but we didn't get below 25 this year...and getting that cold was a rarity. The bubbles are coming out of the return jets...I have two Aqua Genies, so the returns are just below the skimmers.

I'll check all the gaskets, tighten screws and try recirculating tommorrow to see if that clears it. None of the valves are closed. We do have a spillover spa, and those valves are currently closed, but they don't affect anything with the pool returns.

If I do have something in the lines running from the skimmers to the pump, could i use a traditional plumbing snake on it to check?
Or...Any chance the pressure gauge has gone bad? The suction is wonderful on the pump, it just has air in it. Other than that, everything seems great.

But...i am having to educate myself on how to transform my swamp into the pristine blue I fell in love with last year.

Thanks for the info guys.
