Occasionally we all need to add some CYA. Curious if people do what I do...buy 3” inch trichlor pucks and add those until I get back to the desired CYA level. I figure I’m killing two birds w one stone (CYA and chlorine) and it’s nice taking a break from adding liquid chlorine for a few days/week. Do y’all do the same?
 
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.
 
That's the only way I've ever added CYA to my pool. The first two years were more concerned with lowering it from 200+ Now I lose some when I um out to lower CH, but it goes back up when I leave a floater full of pucks when I'm gone somewhere more than three days.

CYA is less than $2/pound on Amazon. Hard to beat.

People here have also had questionable results with CYA bought at Amazon. Caveat Emptor.

I buy my CYA at my local pool store - 8lbs for $20.
 
The brand that I bought is Puri Tech https://www.amazon.com/Puri-Tech-Stabilizer-Conditioner-Protection/dp/B011AD536G/ref=sr_1_2?ie=UTF8&qid=1534046262&sr=8-2&keywords=cyanuric+acid

I have added amounts per PoolMath. It dissolves better than the last brand I had and followup CYA testing increased level as predicted by Poolmath.

My last addition of CYA was about 16 ounces by volume in a sock. I squeezed the sock over and over again over about a 30 minute period and it all broke down in to very small granules small enough to get through the fabric in the white athletic socks (with no hole). 2 days later I tested and had an appropriate increase in CYA. The $2/pound stuff works for me.

Yeah, Steve, Thanks for that link. Had a lot of rain here lately and my CYA dropped significantly. Now I'm SLAMing to get the algae that crept in after I dropped my guard. Love to buy in bulk so it's always on hand and cheaper also.

That's the brand I use as well. I just put it in the sock and toss it in the skimmer. The next day when I'm doing my usual skimmer check it's completely gone. Usually agrees with Pool Math very well for me.
