What is it?

hey waste, you're good!! I do have a brand new stamped concrete deck. Could it be the rain washing some of the dark accent powder along with some of the sealant into the pool. It only seemed to happen that one day of really heavy heavy rain, and it wasnt really that much muck.

Not so sure about 'good', just concious . In the course of my work I see the same stuff in almost every pool with a 'stamped' deck, hope this puts your mind to rest on the 'stuff'.

Lived in Central Los Angeles for three years.

The pollution settled onto the pool daily. This is potentially what it might be - soot.

We used to scrub it out.
