VitaLink ESSENTIALS pH Down is a quality adjuster necessary to control the pH of nutrient solutions.
This concentrated solution (81% phosphoric acid) is formulated for the professional grower. Use in small controlled doses to adjust the pH level of nutrient solutions down. Mix thoroughly and measure with a calibrated pH meter to attain the desired pH reading.
Never combine pH Down with pH Up, they are both aggressive acids !! If your pH solution is too low after adding pH down, add water to bring your pH up again.
