Ive been getting a constant yellowish and brown dust in my pool. I vac out to waste , and the next day its all back ,it actually looks like Tumble weeds that form in deep end and on my slopes.I also had this Problem last year as well. Ive been doing the TFPM this year, but im tempted to go get a Yellow Mustard Algae treatment, but will try and hold off. I just vaccumed again, and scrubbed walls, then Chlorinated to kill whatever I kicked up. Waiting for water level to come back up, then Ill run Pump all night. My #'s today were Total Chl=1.0 Free Chl =1.0 Ph=7.2 Alk=50 Calcium Hardness=70 Stabilizer=40. Chlorine levels were taken before I dumped 2 Gal of 8.25 Bleach in , after I vaccuumed and scrubbed. Thanks for any suggestions
