PH Down

There is no perfect pH. Higher values facilitate cation absorption and lower values help anion absorption : each pH level has compromises. The safest recommended average value is 5.5 to 6.5. Our advice is to stay in the lower part : 5.5 to 6.2.

Terra Aquatica pH- :

Premium pH control and stabilization for hydroponics, coconut and soil

Not a simple acid : Terra Aquatica pH - provides a real contribution to the stability of the nutrient solution

To produce Terra Aquatica pH- we carefully mix 3 acids commonly used alone in hydroponics, to give you all the benefits of each - without the disadvantages.

Terra Aquatica pH- uses nitric and phosphoric acids to realize the initial and most significant pH change 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 because of the phosphoric acids used alone in hard water areas. So, with its special feature, organic citric acid comes into play to stabilize pH changes over time, keeping your solution more stable, and helping to manage calcium excesses in hard water areas.

Use:

CAUTION : Always wear appropriate protections when handling strong acids/alkalis.

pH+/- :

Add to the water or nutrient solution as needed. Re-test the pH and correct it if necessary.
