Having Trouble Cleaning a Pool..

[CarlD]

I didn't mean to be defensive, just to emphasize the importance and value of regular testing and monitoring.

Clearly you're right, laboratory practice is important. You wouldn't get good results if you sucked down a bottle of coke, dipped it in the pool half filling it with the top water, capped it, and let it sit in the bed of the truck in the hot sun (at noon?) on the way to the PS.

Dang! I gotta stop doing that. I might even mess up my truck bed!
