The pool builder is here right this moment fixing an issue with my pool. I don't have time to explain in full detail because time is of the essence.
Basically, the pool needed to be drained to roughly 6" so a crevice that formed under the liner could be repaired.
Afterward, a water truck is delivering 6,000 gallons of water to se the liner, and we are closing our pool for the winter immediately after.
My plan was to use pool math and add the recommended amount of bleach to bring to shock level, pouring the bleach in while the water truck was pumping water in to mix (as the water level will not be high enough to run the pump and circulate).
However, it just occurred to me that I will have next to NO cya because of the drain!
I have the powder CYA but no liquid cya. I know the powder form takes up to a week to dissolve.
What do I do?
If I run out right now to buy some liquid stabilizer, I might miss the water truck and not have any way of mixing the chemicals afterward. If I add the powder CYA, it won't dissolve before closing, and again, no way of mixing.
Any advice please!
Do I just add a small amount of bleach while the pool is filling, say a hail Mary, close it and deal with it in the spring? I can't believe I forgot about CYA.
