Im in the middle of SLAM'ing my pool and today I noticed that micro bubbles are coming out of the return jets. I cant say if I noticed this before or not since the water is becoming more and more clean (THANK YOU BBB!) but I didnt want to discount the micro bubbles being a potential issue.
My setup is a recently installed 1hp 2spd pentair superflow -> S220T sand filter -> Chlorinating dispenser (I have it set to off) -> return jets to the pool.
I also have a polaris booster pump that appears to have 1 return that is in the middle of one of the lengthwise walls. (I do see a little water and small bubbles coming out of this. ) should I cap it since I dont plan on using the polaris?
Water level is about a half inch below the midway mark of the skimmer box.
I put up a video on youtube so you can see it. Hope it helps:
