Lower 7 is a water acidifier, conditioner and line cleaner based on Urea chemically linked to Sulphuric Acid. This technology provides higher safety during handling than others water conditioners on the market.
Lower 7 neutralises dissolved Calcium & Magnesium cations and Bicarbonates in water, keeping the active ingredients in the mixing tank free from cation deactivation and alkaline hydrolysis to ensure maximum efficiency of the irrigation.*
Lower 7 is a powerful water conditioner and irrigation system cleaner, uniquely formulated with Urea chemically bonded to Sulphuric Acid. This advanced composition delivers full-strength acidification upon dilution—while offering the highest safety profile among concentrated acid products. Lower 7 improves water quality, protects equipment, and enhances fertigation efficiency across all cropping systems.
Enhances Nutrient Uptake - Improves solubility and stability of fertilisers in the tank and soil.
Reduces Leaching & Waste - Acidification helps retain nutrients in the root zone, improving fertiliser use efficiency.
Extends Equipment Life - Regular use prevents clogging and corrosion in irrigation systems
Ideal for Bulk Water Treatment - Suitable for large-scale pH adjustment and bicarbonate neutralisation.
Compatible with All Crops & Systems - Effective across all irrigation setups and cropping programs
