Okay, using 22,000 gallons:

To raise the free chlorine FC from 0 to 5 ppm add 27 oz by weight of dichlor. This will also add about 4 ppm of stabilizer (CYA) and drop your pH by about 0.2, meaning we'd get it down to ph=8 without having to do the muriatic acid thing.
To raise the alkalinity (TA) from 30 to 70 add 200 oz by weight of baking soda. Add 1/2 that amount, let it dissolve and circulate for an hour, test again, see where you're at. Add more as needed. This will affect the pH a very small amount upward.
To get 30 ppm of stabilizer you need to add 88 oz by weight. This takes a while to dissolve and about a week before you can test it. Put some in an old cotton tube sock and suspend it in front of a return. It'll be dissolved within a couple days, sometimes less, but will not show up on testing for a while. DO NOT backwash the filter for a week.
Have some bleach on hand. You can get regular unscented household bleach at 6% or you can see if your pool store sells the 5 gallon carboys of liquid chlorine which is about 12%.
If using 6%, 21 oz add 1 ppm FC to 10,000 gallons. Calculate that out for your volume. If using 12%, it comes to 11 oz for 10,000 gallons.

If you're going to follow the BBB method, which is easy and foolproof and inexpensive, di get your own test kit as recommended by Watermom. Then, daily test pH, FC, CC and adjust as needed. Weekly, test TA. Your target levels are pH 7.2 - 7.8, TA 60 - 80, FC 3-5 (see this link for chlorine: http://poolsolutions.com/gd/best-gue...e-chart.html#a, CYA 30 - 50.
