I am trying to identify these discolorations in the deep end of my pool. Algae or stains? They are brown discolorations that don't move when brushed, appear to be slowly spreading (in my opinion), hard to see when the sun is shining on the water.
I was advised they could be organic and go away with time. I haven't seen them fade yet and the pool has had 8+ppm of FC in it for several weeks.
CC in less then .5 and FC overnight test passed.
The stains don't translate well on camera but here are some samples anyway. The stain is browner and more pronounced in person.
