The best way to follow the SS recipe is to use the dichlor. (It also gives you the option to use bleach initially while you get some dichlor.) But, while you are only using bleach, you'll have trouble keeping a chlorine reading as you are finding.

Do you have a Sam's nearby where you can buy Dichlor? Dichlor has CYA in it along with chlorine. The reason you can't keep any chlorine in the pool is because you have no CYA in there. (Cyanuric acid, also called stabilizer. Kind of like 'sunscreen' for your chlorine. Without enough in the pool, your chlorine is quickly lost to the sun.)
