Your pool is about 14,500 gallons.

You will need about 3.5 pounds of stabilizer/conditioner/CYA to start.

After that you need

Muriatic acid - 1 gallon
Bleach - 3 or 4 gallons
Arm and Hammer baking soda - 12 lb bag can usually be found at Sam's/Costco
Borax - 1 or 2 4# boxes

This is the test kit that I use...http://tftestkits.net/splash-page.html

and $55 is a great price https://asp5.secure-shopping.com/sps...cat=1200&path=
