I have a new customer that has a 25000 gallon SWG in-ground vinyl pool that was a green swamp. I tested for FC and of course there was none due to a defective salt cell that is now replaced. Long story short, I could only attend to the pool once a day. So the first day I poured in 13 gallons of bleach and brought the cl reading up to around 31 or so hoping that the high intial FC would last till I could return in the morning. Today the water was better but still cloudy and just lightly green. The FC was back to about 3 or 4. It was going to be a hot full sun day so I poured in 14 gallons of bleach. I returned at noon and the FC was down to 10 so I poured in another 5 gallons of bleach. I have vigorously brushed the bottom each time that I add some more bleach.Thus so far I have a total of 32 freakin gallons of bleach in this pool and I still cannot see the bottom! Tomorrow morning I will return and bring another trailer load of bleach. Any thoughts or suggestions on all of this? I need all the help I can get on this one. Thanks in advance folks!
