Air Bubbles in Return

[rrands]

I have a new pool with looped returns, and noticed a few air bubbles in the return jets - not a ton, but a few - is this normal? If not, is there anything that you would suggest I check?


Thanks!

I figured this one out - my water level was too low, and the skimmer was sucking some air, apparently, though you couldn't tell by looking at it - I closed the skimmer valve, and the bubbles stopped. Then I gradually opened it up to let just some from the skimmer in, and it was fine until I opened it up too much, and then air started coming in. I am putting a couple of more inches of water in the pool to see if that helps, too.
