CYA gone ...

Hey guys, had my cya at 35-40 about 2 months ago, checked today and it is below 30 on the hth test kit from Walmart, so I would say it is roughly. 20-25, we have gotten a lot of rain here the last 2 months, I guess my cya got diluted out, who knows, what's the quickest way to get some cya in the pool ?
 
From the "effects of adding chemicals" section of the poolcalculator.com: 1 8oz (3 inch) puck will raise a 10000 gallon pool 5.5 ppm FC and 3.3 ppm cya. It will also lower ph and TA.

No need to hurry too much getting cya in the water, but you do need to watch your FC level during the time the sun is on your pool so that it does not drop too low. Do you have a swg?

Granular stabilizer is the most cost effective/simiple way to get cya into your pool. Our recommend level is 30-50 ppm cya.
