I finally opened my pool. I added 3 - 182oz jugs of bleach (all that I had). I have about 30 lbs of the OPTIMUM Chlorinating Granules (from wal-mart or lowes made my aqua-chem) left over from last year before I started the BBB. Since my CYA values are 0 (or 9 according to the pool store), I thought that I might use the Chlorinating Granules until my CYA values go up.
According to chem geek, raising FC 10 ppm also raises CYA 6 ppm. Is this relationship for any trichlor? or is it just for the tabs? or the available chlorine?
The granules are:
Boron sodium oxide pentahydrate 8.0%
Other Ingredientsclarifier/filtration enhancer/sunlight protector 20.2%
*Available Chlorine 65%
I guess that I could use them and test the CYA each week, but to me, the CYA test if the hardest to read.
