Caltreat for lowering calcium hardness in pools

[Linda needs help]

Thanks so much for the help so far! The pool is finally clear- it has not been this clear in years! Couldn't believe how much precipitate came out of the water.
Just got the test kit in and tested the pool.
Did the test:

pH 8; Calcium 340ppm; alkalinity 130 ppm; Chlorine, free 1.0 Chlorine 2.0ppm; CYA 25 ppm?

Will stick with bleach for now.

Do we need to add a stabilizer for the chlorine? If so,what type?
1. How often, and how much bleach should be added?
2. How often should we test the water?
3. What do you recommend for raising/lowering pH and alkalinity?
4. How do i attach pictures for you- I have the pictures downloaded, but do not see how to attach.
