My pump quit last Wednesday morning, and thanks to poolcenter.com's speedy 2 full business day order processing, I didn't get a new one until Tuesday with 2nd day air shipping. Also got a new filter from Amazon.
Finally got everything replumbed last night. Needless to say, the pool was a swamp, with the steps covered with green slime and visibility of a foot or so. I didn't have time to put sand in the filter, so I turned everything on running on recirculate so I could chlorinate. Raised the pool to shock level about 7pm, ran to a ballgame, and when I got home at 9 I was down to 4ppm. Boosted it back up, came inside and watched TV until 10:30. Down to 7ppm, boosted it back up and back to the TV. At 12:30 I went out for one last check, boosted the chlorine back up from 6ppm and went to bed.
At 7 this morning, the chlorine was at 6ppm, the slime was completely gone from the steps and I could see the pool bottom out past the shallow end break. No green at all, just the cloudy blue.
No filtration, no brushing, no algaecide and no sweeping, just steady shock-level chlorination for 12 hours.
