15,000 gal IG, water is crystal clear, pool is 2 years old, this morning when brushing my pool, I noticed that when I brushed there was a white powder that followed the brush, I don't think its algae because it is white, could it be the plaster????
here are my pool numbers
My numbers have been consistant, besides the FC, for the past 2 months
I would not think that it is the plaster because my TA and PH are OK
