What is this in my pool?

[Dpooltest]

Trying to figure out what is appearing on the bottom of my pool. This is new this year, pool was opened a few weeks ago, chemical levels normal, first appeared without solar cover, and continues after putting that on. The water is clear and I havent had and CC, or overnight test issues.
Hopefully the pictures are good enough, but it looks like dust balls floating around the bottom of the pool, kinda greyish in the water. I can get them out with a net, and they flatten to like a snot like substance, smaller ones have disappeared through the net. I have vacuumed to waste a few times, so the bottom was clean, and it still comes back. 2 pictures are the balls in pool (top half shows a few) and the stuff when grabbed by my net. Bonus pic, I have a skimmer sock on this is what it looks like.

Any ideas what it is, how to stop / remove it?

Pollen, tree pollen.

Tree foliage, what is in the area that will fly.

OK, so pollen clumps like that? this is year 4 of the pool and its the first time I've seen this. That being said 1 neighbor put up a bunch of arborvitae's in the last 2 years, and they have grown a lot this year. Any way to minimize it? I figured the skimmer sock was full of pollen, but wasn't sure about stuff in pool.

Cotton from a cotton wood tree? Does it look like it is snowing outside?

 

[PoolStored]

Yes, like that...you are fine, this is organic detritus.

Diane, I don't believe there are any cottonwood trees near me.

PoolStored, is there any way to minimize this, or filter more out? It's obviously going through the skimmer sock and sand filter (which has been backwashed).

That doesn't look small enough to pass the skimmer sock.

Why do you say this? I'd use hairnets, not skimmer socks, throw them away at .1$ a piece. Skimmer socks are PITA to clean...

Looks like cotton wood tree debris to me.
