Cyco pH Down 47%

Derived from phosphoric acid, Cyco pH Down is a highly concentrated solution used to lower the pH value (increase the acidity) of a nutrient solution.
Use sparingly – add drops to nutrient solution a little at a time, continue to test pH levels. Repeat application until desired pH level is achieved. The quantity required for pH adjustment will vary depending on the nutrient strength and the purity of your water.
