Athena Pro Balance 10 lb Box | Water Soluble pH Adjuster Powder

The 10 lb Box of Pro Balance pH Up, and Who It Suits

Ten pounds is the size for a room that mixes stock in five gallon batches rather than in totes. At the label rate of a quarter to one pound per gallon, a box makes between ten and forty gallons of concentrate. That is weeks of adjustment for a single room and days for a facility. The formulation is identical to the larger bag and only the packaging changes. It goes into clean water first and into the fertiliser solution second, never dry into a tank. Dose until the solution reaches the target pH, checking with a freshly calibrated meter. It can also be run through an air or misting system where the layout calls for that. A sealed box in a dry cupboard keeps indefinitely, which is most of the argument for the smaller pack. Powder that has taken up moisture cakes and stops measuring predictably.

The Thermal Reaction, and Two Things It Must Not Touch

Dissolving this powder sets off a thermal reaction, and the water gets genuinely warm. Mix it, walk away, and come back when it has cooled rather than dosing straight from a hot jug. Hot concentrate reads a different pH than the same solution cold, which is how set points get overshot. The second caution is metals, and it is the one most often missed. Both the powder and the mixed solution are corrosive to most metals. Aluminium is ruled out specifically, so no aluminium scoops, funnels or tanks. Keep it well away from any low pH product on the same shelf. A respirator belongs in the protective kit alongside eye protection and covered skin. Any pH adjuster is a chemical rather than a nutrient, and this one behaves like one. Growers mixing a single reservoir by hand will find ten pounds lasts most of a year.
