[attachment=0:b7u8knkz]110_4016.JPG[/attachment:b7u8knkz]Is there such a thing as white (gray) algae? I have a few spots on my pool bottom that are growing in size quite fast. One spot is nearly a perfect circle 2 foot and seemed to appear (bloomed) overnight, while the other areas are oblong / rectangular in shape and seem to getting larger. Brushing and acid seem to have zero effect.
In the photo (midway dead center between the tanning ledge and two drain intakes) is the circular white/gray patch that just appeared out of nowhere...almost overnight. It's a little hard to see because of the glare.
At first I thought this was plaster dust and/or scale. Now I do not know what it is!
water test-

pH - 7.4
TA - 80
CYA - 45
