First, my pool is sparkling clear thanks to this site. My neighbor had his pool drained, cleaned and refilled 15 months ago after it was covered for 3 seasons by old owner. He has 30k IG with SWG sand filter and uses a Polaris with booster pump to clean. Runs single speed pump 24/7, a waste but he doesn't care or know better. Pool has fiberglass sides and comcrete bottom with epoxy paint. He never hand vacuums or hand brushes the bottom or sides, only uses Polaris with coarse bag that collects leaves and small debris. He told me yesterday it doesn't get the real fine debris. I offered up my Dolphin robot for a run. It collected nothing but what I assume is fine silt. Looks like talcum powder in suspension. The robot was sending plumes of milky water through the top impeller outlet. Filters took twice as long to clean out after because of the fine debris and while I could see the main drain 9 feet down before running, we couldn't see the drain at all, or really see the shallow end floor below bottom step after cycle over because water cloudy white. I assume it's a huge am,punt of silt.
I thnk he needs to hand vacuum a couple times or more after letting settle, maybe to waste first. Will the sand catch the silt well enough, it seemed to go through robot microfilters at least some. The foam rollers on robot were saturated with milky liquid after using. He needs to scrub pool more, obviously, and maybe get a silt filter for Polaris going forward, but he's more concerned with getting the large among out now. Any other advice? Thanks in advance
