It also adds no calcium and no stabilizer, which is the reason it does not cloud the water and does not push your hardness or cyanuric acid up every time you shock.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow it is sold\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA case of four gallons, which is how service companies buy it.
