    Cal-Hypo and CYA

    Quick question. Just checked my CYA I knew it was going to be low but it's below 20. I still have some cal-hypo pucks laying around from before I found this site. Can I use those to boost CYA? And if so about how much does each puck boost it? Thanks all

    No. Cal-hypo will increase FC and calcium, but has no stabilizer for CYA.

    Hi

    Could you double check those pucks for active ingredient?

    Cal hypo is usually (but not always) in powder form and not pucks. Those pucks could be tri-Chlor which would be stabilized with CYA.

    They are cal hypo skimmer tablets. I will just continue to use them in the kiddy pool the kids use to rinse their feet before getting in the big pool
