Tiny micro bubbles coming from returns

So what are the four speed settings in terms of RPM?

Also, what size is your plumbing and how many suction pipes go all the way from the pool to the pump?

Can you post a picture of your equipment setup?

I found the air leak!! There was a bad o-ring on the suction line from the main drain. Thanks for the help.
