Being a pool pro, nothing is more frustrating then going through the steps of floc ing a swimming pool and it doesn't work. I get the chemicals where they should be. Set the timer on the pump. And nothing. I see the "floc" clumping the stuff together, but a day later or two days later, some of the stuff is on the bottom of the pool, but its not crystal clear.
Then other times, you floc it and the next day. WOW, FIJI water if you know what I mean. Can anyone explain why it works sometimes and why it doesn't others? I'd like to have at least 90% success rate!
