OMG>....Never have i worked so hard like I did today! I...ME....MYSELF...scraped the walls all around the 24ft pool!!!! While doing that, I had tube socks on and rubbed the bottom divots that felt slippery and brushed the bottom the best I could since I couldn't see a thing with dead algae and calcium scales floating in the water....shocked the pool tonite..running the pump/filter..have bumped twice in last 4 hrs. Will bump again at 10pm, then see if I can persuade hubby to walk across the yard after midnite to check the pressure and bump again. Plan on the family getting in first thing in the morning to walk fast around the perimeter to get the water swirling in a whirlpool motion and exit the pool. Hoping for it to mostly settle in the center, then vacuum to waste, add new DE, and keep filtering. We have about 12 kids coming tomorrow for a little pool party for a couple hours. My thinking is to use the kids to splash up a storm, and their feet should help loosen any debris still on the bottom while the filter is still running.
