Champion Muriatic Acid
Product Overview
What pool techs reach for when they need to lower alkalinity and bring stubborn high pH back into balance.
At full commercial strength (31.45% Hydrochloric Acid), Champion Muriatic Acid is the standard specification for fast, reliable pH and alkalinity reduction. Each 1 Gallon container delivers the concentrated strength needed to treat scaling and high total alkalinity without adding sulfates. For homeowners managing upward pH drift from new plaster or salt systems, it reliably handles water balancing across 10,000 gallons or larger installations.

Benefits & What Makes It Different
Full-Strength 31.45% Hydrochloric Acid
Provides commercial-grade concentration to reliably lower pool pH to the ideal 7.2–7.6 range without unnecessary fillers.
Targeted Alkalinity Reduction
Dosing approximately 1.25 pints per 10,000 gallons reduces total alkalinity by 10ppm to maintain proper chemical equilibrium.
Mineral Scale and Stain Cleaning
Effective for removing calcium scale deposits along tile lines, masonry surfaces, and cleaning saltwater generator cells.
Product Details
Hydrochloric Acid 31.45%
1.25 pints per 10,000 gallons lowers total alkalinity by 10ppm; dilute 10:1 with water for pH reduction.
Compatibility
- Never mix directly with chlorine, bleach, or other pool chemicals, as toxic chlorine gas will generate immediately.
- Wait at least 30 to 60 minutes with the pump running after application before swimming, and confirm pH is between 7.2 and 7.6.
When To Use This
Pro Tip
In regions with hard fill water, high evaporation continually concentrates minerals and pulls alkalinity upward; aerating pool water after acid dosing will elevate your pH back to 7.2–7.6 without raising your total alkalinity.
Common Questions & Instructions
How to lower alkalinity in pool quickly using muriatic acid?
To decrease total alkalinity, turn off pool circulation to create calm water, then pour undiluted 31.45% muriatic acid into the deep end at a rate of 1.25 pints per 10,000 gallons to drop alkalinity by roughly 10ppm. Allow it to disperse before restarting the pump.
How do I dilute Champion 1 Gallon Muriatic Acid for pH reduction?
Always pour acid into water, never water into acid. Fill a clean bucket with tap water using a minimum 10:1 dilution ratio, carefully add the Hydrochloric Acid, and distribute it around the deep-end perimeter with the circulation system running.
Will muriatic acid affect both pH and total alkalinity?
Yes, adding Hydrochloric Acid reduces both pH and total alkalinity simultaneously. If your pH drops below 7.2 while you are trying to reach an alkalinity target of 80–120 ppm, aerate the pool using water features to raise pH without raising alkalinity.
