Moderator Note - Moved from here: High CYA did a water dump next steps to keep it down? - Page 2
I too have a similar issue with high CYA. It's been around 100-115 all season. Had kept FC at 2 and high on the 4 end (or so I thought it was high until I saw the chart). Just recovered (hopefully) from a yellow algae outbreak. It wasn't noticeable to most people so hopefully I caught it early enough that I killed all of it. Water was clearer today than it had been in over a week and no sign of algae when brushing.
Back to the CYA... Draining 30% appears to be the best option. Since I will be closing the pool soon, should I drain now and leave it at 70%, drain and refill, or do nothing until next season? The pool will be covered and I have already purchased a winterize kit.
(Not hi-jacking the thread - just tagging alone since we are both in the same situation.)
