Is liquid chlorine or granular shock better?

Both liquid chlorine and granular chlorine are effective in sanitizing a swimming pool.  Different types of chlorine are used in different parts of the country—there are many parts of the country where liquid chlorine is very popular and there are other parts of the country where liquid chlorine is not readily available.  I should note that there are different types of granular chlorine   Each type of chlorine has its advantages and disadvantages.  They are as follows:

Liquid Chlorine     Granular Chlorine
Advantages: very inexpensive, fairly safe, effective    Advantages: long shelf life, fairly strong
Disadvantages: fairly weak, very high pH, short shelf life Disadvantages: more expensive, some types don't dissolve well

Is liquid chlorine or granular shock better?

In the Arizona market, we strongly recommend Hasa liquid chlorine.  We have hard water and the addition of calcium shocks with high undissolvability is not good.
