Adding CYA

[kateinvt]

Add 10 ppm of CYA. That should help the daytime FC loss.

The FAS-DPD test sample does get cloudy. Only think you care about is the color. Once the pink/red is gone, it is done.

How do you add CYA? I’m having the same problem as above.

Add the CYA by using what we call the sock method. Get an old sock (no holes) and put the measured amount of CYA you need. Tie the sock closed and either suspend it in front of a return (hang it from your brush pole works with something weighted on the deck) OR if it still allows flow thru the skimmer, place the sock in the skimmer. Every 15/20 minutes give the sock a squeeze to speed up the process. Please DO NOT follow the directions on the container of CYA to just pour it into the skimmer and don't just toss the sock in the pool as the CYA is acidic and can bleach/stain pool finishes.

Ok. And when buying CYA what do I ask for? Should I get it from the Pool store or hardware store or online?

Any of those. I get mine at Walmart or Home Depot.

CYA aka Cyanuric Acid aka stabilizer aka conditioner.

I add cya when its low by running tablets in my inline chlorinator. Gives you chlorine and raises cya. Even when I had fresh fill, I just ran on tablets until my cya got to 30ppm. Its convenient, maybe more expensive than first adding cya and then using liquid chl
