Canna Organic PH Down

Canna organic PH down contains 50% citric acid. Bacteria and moulds thrive well on citric acid, and therefore also in your nutrient tank. Care should be taken to refresh the solution in the tank on a regular basis. Used for the acidulation of the nutrient solution as an alternative for nitric acid and phosphoric acid. Dosage: Add approximately 20ml organic acid to 100 litres of nutrient solution.
