Aqua Down (pH Lowering Solution 8oz)
18% Phosphoric Acid
Aqua Down pH Lowering Solution feeds your plants phosphorus as you lower pH.
To maximize plant growth, the pH of your aquaponics 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 Aqua Down is Phosphoric Acid.
