Aquadown Ph Lowering Solution 32 Oz
18% Phosphoric Acid
AquaDown pH Lowering Solution feeds your plants phosphorus as you lower pH.
To maximize plant growth, the pH of your aquaponic fish tank water should be 6.8 – 7.0. pH can reach unacceptably high levels when high pH water is added, pH unstable media, such as rock wool and granite gravel products, are used,or an anaerobic zone develops in your grow bed.
The active ingredient in AquaDown is Phosphoric Acid*.
Directions: Use to lower pH in an aquaponics system when it is 7.6 or higher to bring it down to 7.0. Rapid changes in pH can be harmful to fish so use sparingly and adjust over several hours or days. Add to system a little at a time, wait for it to distribute throughout the system, then retest pH. Repeat, until the desired pH is reached. The quantity necessary to adjust pH will vary depending on the nature of the grow media and the carbonate level of the water in the system. To find out how much to use in your system we recommend a technique called titration. Take 1 gallon of water from your tank, figure out how much AquaDown you need to decrease the pH to the target level, and then multiply that by the number of gallons in your system.
Storage: Store in a cool, dark place.
