Where to buy CYA? & acid ?

[PJM361]

Of course there isn't anything on the muriatic label http://www.wmbarr.com/ProductFiles/G...06%20J5807.pdf so I had to start searching and found out it's <25% hydrochloric acid http://www.wmbarr.com/ProductFiles/K...%206-10-08.pdf
How many ounces of muriatic acid per 10K gallons to lower PH?
Also the Aqua rite manual says the CYA should be between 60-80 ppm, I thought I read somewhere on here that it should be between 30-50ppm. The bag at the store said between 35-100ppm. Also the 12lbs called for in the aqua rite manual was to raise it to 80ppm.

How many ounces of Muriatic acid to lower your pH will depend a lot on your TA--the higher the TA, the more acid it will take to drop the pH than at a lower TA. It also will depend on how low you want to drop it. With a SWCG, though, dropping your pH is going to be a continual thing, and the acid lasts a long, long time, so I would go ahead and get a gallon of it and you can go from there.

Regarding your CYA, go with what your SWCG manual says. Each model requires a different amount, and it is designed to extend the cell life and let the unit work the most efficiently, so that's what you want to go with--and I believe the SWCG gurus on this forum say that you need to be at the high end of that range.
