Terra Aquatica pH Down can do more than a pure acid: it makes an important contribution to the nutrient balance of the solution.
For the production of Terra Aquatica pH Down, T.A. combines the strengths of three acids that are usually used individually in hydroponics, which has disadvantages, into a balanced mixture that has only advantages.
Phosphoric and nitric acids perform the main task of regulating the pH at the beginning in Terra Aquatica pH Down. Their ratio is adjusted so that it does not affect the N/K ratio in the growth and bloom phase and no residues form on the tank surface, which happens with phosphoric acid alone in hard water. Then biological citric acid takes over. Thanks to its buffering effect, it compensates for pH fluctuations that occur in the further course, keeps the nutrient solution stable and compensates for calcium surpluses in areas with hard water.
Caution: always wear appropriate protective clothing when handling strong bases.
pH correction: Add the required amount to the water or nutrient solution. Measure the pH again and correct if necessary.
