I’m at my wits end with this brown dust repearing at the bottom of my pool. All levels are balanced and within normal range. The water is crystal clear. When we first opened pool I did a SLAM process then after the process few days after added floc let pool recirculate for hr then turned filter off completely for 8hrs then vaccumed debris/algae that accumulated on bottom to waste . Came back the next day vaccumed again to waste any remaining debris. Kept seeing this brown dust reappear so I vaccumed again to waste. Pool looks great but it always comes back and accumulates in little clumps along the bottom. I brushed it to see if it could possibly be sand from the filter but nope it disperses into a cloud and I can see bits of it floating through the water when I touch it. It always settles back down to the bottom and there is nothing along the walls when I brush them.
