1) add salt to the level suggested by your SWG manufacturer, usually 3000-4000 ppm. Allow to dissolve fully.
2) add cyanuric acid (CYA), aka stabilizer, to 70 ppm
3) add muriatic acid to lower or borax to raise your pH to between 7.2 - 7.8
4) add plain unscented bleach, aka liquid chlorine, to raise free chlorine (FC) level to 10 ppm
Amounts to add can be determined by using the Pool Math page on this site.
Monitor closely for a few days using one of the two recommended test kits, either the TF-100 or the K2006. Do not trust test strips or pool store testing. Our methods demand that you perform your own testing. That's all we will trust.
Adjust your SWG to maintain your FC at or above 9 ppm. Drop below that and you will be inviting algae to take hold.
Pour margaritas and enjoy your pool.
