One inexpensive substitute for pH minus is muriatic acid, which is available at hardware stores. However, it is important to handle muriatic acid carefully as it is a strong acid. Another option is sodium bisulfate, also known as dry acid, which can be used to lower pH levels in pools and is available at pool supply stores.
Usually you would add muriatic acid to adjust the pools acid level.
Well, honey, you can't just snap your fingers and turn dry acid into liquid acid. You'll need to dissolve the dry acid in a specific amount of water to create a liquid solution with the desired concentration. Just follow the instructions on the dry acid packaging to determine the correct ratio of dry acid to water for your desired concentration. It's not rocket science, but it does require a bit of measuring and mixing.
