Chemicals seem to have no effect

Cya is not naturally in water. So the fill is 0 and you need 10k gallons worth to 30 :)

CH 250 in the fill water is a good on its own. It will rise soon enough.

Hi. I have not purchased CYA before (no surprise). I'm checking out Leslies and I can't see a form of pure CYA. I did read through the TFP section on this and it sounds like I want to steer away from lots of additional ingredients. I live in zip code 85377. Ideas on a product to buy and where?
I found this type of product through Amazon. https://a.co/d/3c65pGc Can't get this for 4 days
Found this https://a.co/d/aVIIfAO doesn't look "pure"

Home Depot and Lowes too. All 3 have 100% stabilizer / CYA in the pool aisle

Pool Math says Target CYA of 30 is out of range. We know that's wrong. :) Just read somewhere LOL that I should add 1 pound of CYA per 4000 gallons of water.

Now I get add 40 oz by weight to reach your target. using dry stabilizer. Should it be a liquid? (still says that 30 is outside the range).
40oz by weight is just how you measure dry things. It is the same as 2.5 lbs.

Liquid cya is quite expensive & doesn’t work well unless you use an entire bottle- looks like a whole gallon of liquid would yield 37ppm cya in your pool volume. If you choose to use liquid be sure to rinse the bottle well in the pool.

OK. I'm finding that most of the cyanuric acid products say 98.5% cyanuric acid and 1.5% other ingredients. Is this pure enough? I've checked Walmart and Lowes. Our Lowes only has a product called Pool Mate and the local Walmart only has HTH and both products are called Chlorine Stabilizer. I'm sorry to be back and forth on all these details; but, my husband isn't into this stuff. He likes that I'm into it and he's willing to go buy everything. I just need to give him a specific product to pickup as I'm working :) BTW Pool is full and I need to do tests in the AM. :)

Chlorine stabilizer = CYA.
