For the first time in years my CYA is headed for the low end...30-35. I had a post last year re: CYA levels for sunny pools where a reply was that I could go 60-80 for an all day sunny pool. The recommended level for vinyl using bleach is 30-50. Would it be worth it to increase CYA to say 70 for my situation (once I get through shocking which is this weekend's activity).
If so, I have about 6 pucks left from last year, would it be OK to use them to gain a little CYA or should I just use the pure CYA? I saw another post on the cost for various additions due to their impact on other parameters which need treating but I got a little overwhelmed. I'm just looking for the bottom line or should I not worry about it?
