## Description

Product description

Review: Does what it says it’s supposed to do - Raise the pH it was good. It works good.
Review: Powerful Downer - Great stuff. I cautiously added just a little to my ten gallon reservoir, ph took a good dive. Had to add more tap water to bring it up to 6. I would recommend a ph meter. As water may differ in ph, so would the amount of solution needed per gallon. Add very small amounts, and test. This stuff is hands down solid.
