Mine went from green to blue in one day. Vacuumed up as much organic stuff as possible and then slammed it with bleach. Next day -- no green. Within a couple more days of continued dosing with bleach and filtering and it was no longer cloudy. Hope to swim in a couple of weeks. Out of town this weekend for my nephew's wedding, so the solar heater probably won't get hooked up until next weekend. Then, we just need some sunny days! Lots of rain this past week. Rain most every day all week and I think they are saying more for the weekend. Hopefully not TOO much. We don't need any more water around here for awhile. During one of the 24 hour periods, we got between 2-3 inches. Lots of areas had flooding. Send sun!!!
