Took my pool cover off on Sunday, and had clear blue water. We had a couple of rains, and off/on fill up from my well and I was finally able to turn on my pump/filter. Nothing at the bottom of the pool floor. Within 5 minutes of running it, I’ve got these spots showing up. I had them all last year and whisp up into the water when disturbed.
I slammed last year, and it didn’t help. Water is still too cold to have algae. And I have great water chemistry (and passed OCLT).
Why would this all of a sudden show up after I start my pump/filter?
Ignore the deck, in the process of repairing & painting!

). In fact, I had this same issue after we moved in 3 yeas ago, so I changed 1 year old pool sand last year. So this year would be the 2nd year. I guess it could be dirt & pollen since we live across from corn/bean fields 
That’s what I chalked it up to until this year. Just frustrating that about 5 min after I turned on the pump, it looks like this and I’m at a loss
