I have an 8.5x5.5 ft Intex soaking pool until me and my wife save enough for an inground. We're in Florida so it helps beat the heat. The problem is we continue to get a yellowish fine dust all over the pool's bottom after a week of changing the water. I'm not sure if it's algae or pollen or dirt. There's a few palm trees from the neighbor next to it but full sun otherwise. We are running a 1,000 gph pump 6 hours a day, use 2 chlorine tabs in a floater and the filter does not appear to be in need of replacing. Just took pics and chlorine tabs still have life at the time. We have also been using a pool vac every few days. This comes back quickly. Please let me know what can be done. Too much trouble to keep draining and cleaning. It's about 600 gallons. Thanks.
