I have a simple hydroponic tower with a 5 gallon water capacity and this pH down works excellently. It doesn’t take much to lower the pH at all, the insurrections for adding are clear and the results speak for themselves.

Works very well, reduces the PH in my beer with just pouring it into the water.

It's pH down to use with hydroponics / growing so nothing crazy to write about. Use as needed whenever your water is above the ideal range. I bought mine in 2021 and have had some inconsistent results with it recently where a small amount brought the pH down more than it usually would. That's happened three times now so I took some time to shake it and hopefully that resolves the inconsistencies. If I can't figure that out then I'll replace it since I don't like not being able to estimate how much to use for a certain pH and volume of water. MSDS sheet from 2021 I found indicates its 10-17% phosphoric acid. Therefore I put value for money pretty low since you can buy food grade phosphoric acid at 85% for pretty affordable prices and dilute it yourself. If your churning through this stuff and want a more affordable option I would suggest you look into that.
