Wavy line on pool surface

[colin313]

Just opened pool and noticing a wavy line that forms on the surface from one end to the other only when the pump is running. This is the first time seeing this. Hard to tell from the pictures but any idea what it is and how I get rid of it?

Hmm is there a return pool jet set in the direction?

Return jets are pointed down at roughly 45 degrees, to the point the surface water doesn’t move, but yes the jets are pointed in that direction.

That would be my only guess. Maybe try point them a different direction and see if the problem resolves?

I played around with them and I think it went away. Something so simple thanks! I thought that it might have been some sort of oil substance but wouldn’t have made sense since it’s only visible when the pump was on.

No problem. Glad I was able to help.

Have the same in my pool. Weird to see.

I spoke too soon and it’s actually back. I thought I resolved it by playing with the eyeball return jets, but seems to still form right around the skimmers. Wonder if there’s some sort of current coming from the skimmer when meeting with the current from returns that’s causing it to form.

Same place as mine. Right in a corner where the return pushes water and skimmer around the corner

Notice my skimmer is forming a current, pushing water and debris away from it. In turn it is creating that wavy line in the water I was referring to. To note, my return jet is at the opposite side pointing directly at the skimmer so I’d think that would force debris into it.
