Product Overview

Champion Muriatic Acid is a powerful pool and spa water-balancing chemical used to lower pH and total alkalinity for clearer, more comfortable water. It’s commonly used to correct high pH, improve sanitizer efficiency, and help prevent scale formation on pool surfaces and equipment. This 4-gallon case includes four 1-gallon jugs for convenient handling and storage.

Ideal For

• Lowering high pH in pool or spa water

• Reducing total alkalinity when levels are elevated

• Helping prevent scale buildup on tile lines, heaters, and salt cells

• Improving chlorine effectiveness by restoring proper water balance

• Routine water care in pools with frequent pH drift (including many salt pools)

Key Features

• Fast-acting water balancer for quick pH and alkalinity adjustment

• Helps reduce conditions that can lead to cloudy water and scaling

• Convenient case pack — 4 x 1-gallon jugs

• Useful for pools, spas, and general pool maintenance needs

Benefits

• Promotes stable water balance for better swimmer comfort

• Supports more efficient sanitation when pH is in range

• Helps protect pool finishes and equipment from scale-related wear

• Provides reliable performance for ongoing maintenance and corrections

Product Details

• Type: Muriatic Acid (Hydrochloric Acid solution)

• Size: 4 Gallon Case (4 x 1 Gallon)

• Application: pH reduction / alkalinity reduction (pool & spa)

How to Use

Test water first. With the pump running, carefully add the recommended amount to the pool—typically by pouring slowly in a controlled stream in a deep area or as directed by your pool professional/test results. Allow water to circulate, then retest and adjust if needed.

Storage & Handling

• DANGER: CORROSIVE. Use appropriate personal protective equipment.

• Store upright in a cool, well-ventilated area away from sunlight and heat

• Keep away from metals, chlorine products, and other pool chemicals

• Never mix with chlorine, bleach, or other chemicals (can create hazardous fumes)

• Add chemical to water—never add water to acid

• Keep out of reach of children and pets

Customer-Facing Q&A

Q: What does muriatic acid do in a pool?
A: It lowers pH and can reduce total alkalinity, helping restore proper balance, improve chlorine efficiency, and reduce scale risk.

Q: Is this the same as hydrochloric acid?
A: Muriatic acid is a common name for a diluted hydrochloric acid solution used for pool maintenance.

Q: Can I use this in a saltwater pool?
A: Yes. Many salt pools experience pH rise, and muriatic acid is commonly used to bring pH back into range.

Q: How do I add muriatic acid safely?
A: Add slowly with the pump running, avoid splashing, and follow label directions. Never mix acid with other chemicals and keep it away from chlorine products.

Q: Will this help with scale?
A: Keeping pH and alkalinity in range helps prevent scale formation on surfaces and equipment like heaters and salt cells.
