Do you have a Sam's Club near you? If so, you would do well to buy some of their Dichlor and use that to start your pool instead of bleach as it will add CYA (stabilizer) as well as chlorine. Without enough CYA in a pool, you will quickly lose your chlorine to the sun. It will also help to lower your pH since it is acidic.

I think it would be best if you would just ignore the Intex pool care plan. It will be difficult to try to combine those instructions with the SS Recipe.
