BALANCE PAK 300 4 KG BIOGUARD
Nobody warns you about calcium hardness when you become a pool owner. It's not on the standard test strip. The consequences are invisible until they're not — and by the time you see pitting on your marbelite or a failed pump seal, the damage has been compounding for months. BALANCE PAK 300 is the co

Your pool surfaces stop losing material to the water. Water below 150 ppm calcium hardness is aggressively unsatisfied — it extracts calcium from whatever it touches, including your plaster and marbelite finish. The 4 kg size gets large pools into the protective 200–400 ppm range in a single treatment, where the water is satisfied and leaves your surfaces alone.
You extend the life of every piece of equipment the water touches. Pump seals, heat exchangers, copper fittings, metal ladders — all are attacked by calcium-deficient water. A heat pump replacement costs R8,000–R20,000. This is the R300-equivalent insurance that prevents that scenario.
Significant volume correction without multiple smaller doses. When you need to raise calcium hardness by 100+ ppm in a large pool, a 1 kg bag becomes a frustrating multi-trip exercise. The 4 kg size handles meaningful correction properly — one treatment, correct result.
BioGuard calcium chloride at the concentration and purity you need. Professional-grade formulation for reliable, measurable water correction — not industrial-grade calcium chloride with variable purity and unpredictable results.
Nobody warns you about calcium hardness when you become a pool owner. It's not on the standard test strip. The consequences are invisible until they're not — and by the time you see pitting on your marbelite or a failed pump seal, the damage has been compounding for months. BALANCE PAK 300 is the correction for large pools or significant hardness deficits. The pool problems you prevent are always cheaper than the ones you repair. This is one of the most cost-effective prevention decisions available for a pool owner.
