When I took over my new pool in April, my CYA was around 70. Since then we have had a ton of rain (and subsequent draining), performed a SLAM and now water is the most beautiful thing ever! I measured my CYA yesterday and it is now 35. I do not get a ton of sun (it's hot here, but my water is cool compared to other pools in the area, like 84), as I have many trees providing shade. My daily FC loss is around 3, depending on how much the kids (and their friends) swim by day.
So, two questions...am I OK at 35? Should I get it up to 40-50? Question 2, if I do need to increase, since I have a bucket of pucks I bought when I knew nothing, is it OK to use those for a bit until my CYA is at recommended levels?
My real plan was to have a low enough CYA level come late July, as I am heading out of town for 2 weeks, and I wanted to float pucks while I am gone.
