Thank you!
Until you get stabilizer in the water, you're going to need to keep your chlorine in the 1-3 ppm range. In a 23000 gal pool, it takes just under 1/2 gallon of 6% bleach to raise your chlorine by 1 ppm. With no stabilizer, the sun is going to eat it up pretty quickly, so plan on adding your bleach for sure at night and then probably bumping it up once during the day.

Most people target about 20 ppm stabilizer, and then work from there depending on how long your chlorine holds. For your size pool, you're going to need about 3 -3 1/2 lbs stabilizer to accomplish this. WalMart sells a 4 lb container in their pool section. Don't broadcast it like the directions say--either put it in a sock and hang it in front of a return, or dissolve it as much as you can in water and put it in through the skimmer--just make sure if you use this method that you don't backwash for at least a week because it takes several days for the CYA to register on tests. In the meantime, you're going to need to do the daily chlorine additions until the CYA is available to help shield your chlorine from the sun.
