This is my first full summer with the BBB method. Last summer and earlier this summer, my CYA was high so I didn't have to add as much chlorine. My CYA has now drifted down to 27 (per pool store/40 per my test kit) and I feel like I am adding chlorine a lot - I usually add 2 bottles a day and if I don't, chlorine drops to almost 0. My pool stays covered except when we are swimming, so I think that would help with the loss to sunlight?
My question is if I should raise my CYA level a bit? If so, can I use some of my shock packets I have left over from my old ways? I haven't been able to get bulk chlorine so it is time consuming and a pain to add so many bottles each week.
Thank you for any input!
