AquaDown pH Lowering Solution

How AquaDown pH Lowering Solution works:

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 plan to make adjustments over several hours or days. Add to your 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.
