You need to keep your Cl level at about 3 ppm, so when you use the bleach calc,put in your pool gallons, the strength of bleach you have, and put 1 in the ppm increase blank, and hit calculate--it will give you the amount of bleach you need to raise your Cl by 1. Test your water and find out what's already in the pool,then figure out and add the difference to get it back up to 3.

WalMart sells a form of dry acid called pH Down that will also work to lower your pH if you don't want to deal with the muriatic acid. Muriatic is a little cheaper and works better, but the fumes are pretty nasty, so be careful with it if that's what you choose. Don't give up on the pool, you can do this!
