How much do I buy of the following:

Unscented bleach
Muriatic Acid (33%)
20 Mule Team Borax
Arm&Hammer
CYA/Stabilizer - is there a brand that is preferred?
Cal-hypo

I dont know how many gallons the inground pool is. I will probably throw out all of the previous owners pool chems so I want to know how much do I need to buy of each. I know it depends on what my levels are and size of the pool, but I just want a rule of thumb. How much do you keep in your garage?
