PoolFix 12.5% Liquid Pool Shock

PoolFix Liquid Chlorine – Commercial-Grade 12.5% Sodium Hypochlorite Pool Sanitizer (1 Gallon)

PoolFix Liquid Chlorine delivers commercial-grade sanitation power in a ready-to-use, no-mix formula. At 12.5% sodium hypochlorite — the highest concentration available for pool-grade liquid chlorine — it acts fast to eliminate bacteria, algae, and other contaminants, restoring water clarity with every dose. Unlike stabilized tablet or granular chlorine, PoolFix Liquid Chlorine contains no cyanuric acid and contributes zero calcium hardness buildup, making it the preferred choice for pool service professionals managing water chemistry with precision.

• ✔ Commercial-grade 12.5% sodium hypochlorite — the maximum pool-grade concentration; roughly twice the strength of household bleach and significantly more effective per ounce than lower-concentration alternatives
• ✔ Fast-acting, ready-to-use formula — no mixing or pre-dissolving required; pour directly into the deep end with the pump running for immediate distribution
• ✔ Zero cyanuric acid (unstabilized) — won't contribute to CYA buildup, ideal for commercial pools, indoor pools, and any application where stabilizer levels need to stay controlled
• ✔ No calcium hardness increase — safe for all pool surface types including plaster, colored plaster, aggregate, vinyl liner, and fiberglass without scaling risk
• ✔ Compatible with automatic chemical feeders — suitable for use with peristaltic metering pumps and chemical controllers in commercial and high-volume residential installations
• ✔ Dual-purpose sanitizer and shock — use for routine daily maintenance or super-chlorination; 1 gallon treats 10,000 gallons to approximately 5 ppm for startup or shock dosing

Maintenance dosage: approximately 11 oz per 10,000 gallons to maintain 1.0–4.0 ppm free available chlorine. Shock dosage: 1 gallon per 10,000 gallons. Add in the deep end with circulation running; maintain target pH of 7.2–7.6. Store in a cool, dark location away from direct sunlight to preserve concentration. Do not allow bathers to enter until free chlorine tests at 4.0 ppm or below.
