100% soluble potassium carbonate pH-up — precision-mixed for advanced commercial fertigation.
Athena Pro Balance is a fully water-soluble, powdered potassium carbonate pH-up engineered for professional cultivation operations running advanced injection systems. Mix to a custom-strength concentrate and dial in pH adjustment to suit your water source, injection rate, and system requirements — no liquid pH products, no silicate clogging.
Athena Pro Balance is a powdered, water-soluble pH-up product built on an ultra-pure potassium carbonate formula. Unlike liquid pH-up products or potassium silicate-based alternatives, Pro Balance dissolves completely into a high-concentration stock solution with no particulates, no residue, and no silicate buildup that can foul venturis, orifices, or pressure-compensated drippers over time.
The powder format puts you in control of concentrate strength. Mix at 0.25 lb per gallon for a mild, fine-tuned solution or push to 1 lb per gallon for aggressive correction — then calibrate your injector ratio to match. That flexibility is the core advantage over fixed-strength liquid pH products when your source water alkalinity varies seasonally or facility to facility.
Pro Balance is part of the Athena Pro Line, a fully dry-soluble fertilizer programme designed for stock-tank and injector-based fertigation at commercial scale. It is the pH management component that pairs with Pro Grow, Pro Bloom, and Pro Core across all growth stages.
Pro Balance is the right call for licensed cannabis and hemp operators running RO-sourced water through automated injector systems — Dosatron, Netaflex, Rhythm, or any venturi-based dosing setup. RO water strips carbonate alkalinity, producing an unstable, low-buffering-capacity solution that swings pH between irrigation events. Pre-treating the RO feed with Pro Balance establishes a stable pH baseline before nutrients are introduced, reducing drift and the number of corrections needed mid-cycle.
It is equally well-suited for operators who have experienced clogging or silicate scale from potassium silicate pH-up products. Because Pro Balance is formulated from potassium carbonate — not silicate — it flows through venturis without the mineral deposition that eventually restricts flow or fouls check valves.
Multi-site operators, management service companies, and head growers speccing a single nutrient programme across multiple rooms or facilities benefit from the consistent, scalable nature of a dry concentrate: bags store longer than opened liquid, and batch-to-batch performance is predictable.
100% soluble potassium carbonate — no particulates, no sediment, no silicate scale in irrigation lines. Concentrate mix rate is adjustable: 0.25 – 1 lb per gallon of water (40 – 120 g/L). Dial in the ratio that lets you hit target pH at a sensible injection percentage for your system.
Important handling note: dissolving Pro Balance in water is an exothermic reaction — the solution heats up during mixing. Allow the concentrate to fully mix and return to ambient temperature before introducing it to your system or reservoir. Always calibrate your pH meter before measuring the mixed solution.
Safety: potassium carbonate is corrosive to most metals. Do not expose the powder or any mixed solution to aluminum. Store away from low-pH products in a well-ventilated area. Wear appropriate PPE during mixing — respirator, eye protection, and skin coverings. Pro Balance is available in 10 lb and 25 lb sizes through HSC; the 10 lb box (SKU: PRO-UP-10) is the standard commercial entry point.
In a stock-tank fertigation layout, Pro Balance is mixed first — always add pH adjustment to clean water before introducing base nutrients. This sequencing prevents localized precipitation when high-pH concentrate contacts concentrated fertilizer salts. Once the stock pH solution is prepared, cooled, and confirmed on a calibrated meter, it feeds into the injector system alongside your Pro Grow or Pro Bloom stocks.
For facilities managing multiple strains across different rooms with different target pH bands, the adjustable concentrate strength means a single bag of Pro Balance can serve varied injection ratios by room without stocking multiple liquid pH products at different dilutions. Adjust mix rate and injector percentage independently for each zone.
Pro Balance is compatible with the full Athena Pro Line programme and can also be used to condition water for any other dry or liquid nutrient brand — it is not chemically exclusive to Athena nutrients. This makes it a practical choice for operations that run Athena as a base programme while incorporating third-party additives or supplements.

Potassium silicate products can leave mineral deposits in venturis and pressure-compensated drippers over time, eventually causing flow restriction or clogging. Potassium hydroxide is highly caustic and can be difficult to handle safely in large-volume operations. Pro Balance uses an ultra-pure potassium carbonate formula that is 100% soluble, flows cleanly through advanced injector systems, and produces no silicate scale in irrigation lines.
Start at 0.25 lb per gallon (approximately 40 g/L) and adjust your injector ratio to achieve the desired pH lift. If you find you need very high injection volumes to move the needle, mix the next stock batch at a higher strength — up to 1 lb per gallon (120 g/L) — and reduce the injection percentage accordingly. The right combination is whichever lets you hit your target pH with a practical, controllable injection rate for your system.
Dissolving potassium carbonate in water is an exothermic reaction — it releases heat. This is normal and expected. Always allow the mixed concentrate to cool completely and fully dissolve before using it in your system. Introducing a hot solution to a reservoir can affect plant roots and may give an inaccurate pH reading. Calibrate your pH meter after the solution has stabilized at ambient temperature.
Add Pro Balance to clean water first, before any base nutrients or other fertilizers. This prevents localized high-pH zones that can cause precipitation when pH-up concentrate contacts concentrated nutrient salts. Confirm pH of the prepared stock solution with a calibrated meter before injecting into the main line.
Yes. Pro Balance is a standalone pH management product compatible with any dry or liquid nutrient brand. Its potassium carbonate chemistry has no interaction with specific nutrient formulations that would make it exclusive to Athena products. Just follow the standard sequencing rule: adjust water pH first, then add nutrients.
