What could this stain be?

[Ribbod]

I know its hard to tell in these pics.. Just got done with my SLAM, FC is at 24 (CYA 60) , Passed OCLT (confirmed 3 times) and water is clear... I did add Clorox Pool Salt yesterday and then noticed these green spots - they wont budget when brushing.. Could it be staining from the salt?

We don’t recommend Clorox pool salt due to the contamination it has that stains pools.

Try and rub a paste of Vitamin C in a sock on the stains.

Yeah, i figured that was the culprit... I have read about Clorox staining, but it had never been an issue until this year and have used it consistently for the last 4 years - UGH!

It works until you get a contaminated bag. They do not have consistent quality controls.

What kind of sock do i use? I use a knee high to dissolve my CYA- will that work? And how much Vitamin C do i need? I assume ill buy the biggest bottle they have....
