Hello,

I am having a period (last 2 weeks) of floating stuff in pool that looks like pieces of tissue. I catch it in the screen skimmer and when you touch it is almost disappears. Lots of little flakes.

I have checked the FCL level and it never went below 3ppm. for months.so I thought it was a proper environment.

So... If I have a whitish / grey matter floating in my indoor pool I should shock
to 10+ ... 20+ ? level and run filter all the time until it disappears ?

Looks awfull.

Any other ideas?
