I started this year with a horrible pool opening............it was the worst it's ever been, just nasty. I had thrown about 30 lbs. of granulated chlorine at it with little results. Then I found TFP, and read, and read, and read. And I found that lots of things I was reading about was what I had been dealing with the last couple of seasons. So, I upgraded my testing and found, wow, my CYA was off the charts. (hmmmm, no wonder nothing was happening) My local pool store doesn't even keep CYA reagent for kits, so, I don't suppose my tests I ever took in to them was ever tested for CYA. So, I dumped 70% of the water and refilled and even then, CYA is still 70! I can work with that through the season with refills after back washes. After a 3 day SLAM, here it is.poolresize.jpg
Now, I can work on the TA by aerating, and the CYA by refills after backwashes through the season as I'm using nothing but bleach, and get my daily bleach additions zero'd in.
Am I going about this right? What am I missing?
Thanks TFP, I'm looking forward to this season!
