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.
