Instead of hitting your system with strong acids, it uses a citric acid formulation that keeps things chlorine-free and prevents the mineral scaling that trashes your equipment over time. If you're running hydroponics or dealing with hard water, this is worth the step up from standard pH down.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eVeg+Bloom PHLO is a non-ionic pH down product designed to lower water and nutrient pH to the sweet spot (5.3–5.8) without adding unnecessary minerals or chlorine to your system. Unlike traditional phosphoric or sulfuric acid adjusters, PHLO uses citric acid and saponin-based chemistry to drop pH safely whilst actively preventing biofilm and mineral deposits in your reservoir and irrigation lines. It's the kind of product that stops small problems becoming expensive ones.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003ePHLO sits in a different category to standard pH down products.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003evs. Phosphoric acid pH down:\u003c\/strong\u003e Both work, but phosphoric acid adds phosphorus to your system.
