Good product
Works as advertised! Exactly what I was expecting. I use this on my well water which is very hard. I add about 2.75 ml to each gallon of water to bring down the PH to approximately 6.25. I'm a repeat customer ( it's a good product).

Stable PH
This product is a phosphoric based acid. Others out there are basically vinegar and do work, but require constant treatment and monitoring. In my NFT system this product works better for a stable PH value.
