Microbubbles

Ot appears to be the return pump as the problem.
When I put filterfloss in the pump,the microbubbles go away
What is another pump to buy that has a filter system?

Assure there is adequate height of water over the return pump. Slowing pump slightly will help accomplish this

Post a pic of the return might help !

As long as there is filterfloss in the pump, no bubbles.

I wouldn't have filter floss in the pump itself.

I expect the floss is just restricting flow. Perhaps that white corrugated pipe has an air leak. See if it stops by raising the level above the end of the white pipe.

Edit - thinking about it I don’t think a ventury would be created by a return pump with that head height, perhaps the lower flow is just increasing the sump water level. Is an air tornado evident above the pump?

No.
