Highly concentrated - use sparingly
Our pH adjustment solutions are specially prepared for use in hydroponics. They are extremely concentrated and care should be taken when in use. Our pH Down is 81% phosphoric acid and pH Up is 24% potassium hydroxide. For growers in very hard water areas we also offer Nitric Acid pH Down as an alternative to phosphoric acid because it affects the composition of the nutrients less. Keep away from children.
Please pay special attention whilst handling these products as they can be hazardous if used incorrectly. Please see the downloadable safety sheet for guidance (see datasheet download above).
