There is no perfect pH. Higher values facilitate the absorption of cations and lower values help the absorption of anions: Every pH level has compromises. The safest recommended average value is 5.5 to 6.5. Our advice is to stay at the bottom: from 5.5 to 6.2.

TERRA AQUATICAL pH- :

Premium pH control and stabilization for hydroponics, coconut and soil.

Not a simple acid: T.A. pH- provides a real contribution to the stability of the nutrient solution.

To produceT.A. pH- 3 acids are carefully mixed, commonly used alone in hydroponics, to give you all the benefits of each - without the disadvantages.

T.A. pH- uses nitric and phosphoric acids to realize the initial and more significant change of pH in your water, and the mixture of the two means no disturbance to your N/K proportions throughout the cycle - and no residue on the surface of your tank due to the phosphorous acids used alone in harsh water areas. So, with its special feature, organic citric acid comes into play to stabilize pH over time, keeping your solution more stable, and helping to manage calcium excesses in harsh water areas.

HOW TO USE pH- :

Attention: It always wears adequate protections when handling strong acids.

To change the pH: add to the water or nutrient solution as necessary. Test the pH again and correct it if necessary.
