SWCG-creating bubbles in return jets

Hi All.
I have a new inground plaster pool. It was installed with a aqua rite salt water system. Initially it had a T3 cell for a 18k gallon pool, obviously too small so before I added salt I installed a T925. Ever since I switched it out to a T925 (Hayward) I’m getting bubbles in two of my return lines . They are tiny bubbles and the jets are noisy. The pump basket looks good. No major bubbles and the pressure on my 325sq foot filter sits right around 10-11 and hasn’t moved since install. The pressure from the jets is also strong and hasn’t changed since I installed the 925 Swcg and added salt to the pool. Any ideas what the bubbles are? I don’t understand why I’d all of sudden be getting air in my system. Btw, I have a single sped super pump, if that matters. Any help or advice would be great!
