Muriatic Acid - 1 Gallon
Product Overview
A proven choice for lowering pH and total alkalinity when dry acid isn't efficient enough for the job.
This 1 Gallon container of Pool 360 muriatic acid contains 31.45% HYDROGEN CHLORIDE, the standard specification for professional-grade pH management. At 20 degrees Baume, it provides the strength required for both routine water balancing and more intensive tasks like acid washing plaster surfaces or cleaning masonry. We stock this 128 FL OZ bottle because it reliably handles high-alkalinity scenarios that would otherwise require excessive amounts of dry acid.
Benefits & What Makes It Different
31.45% Active Ingredient
The high concentration of HYDROGEN CHLORIDE ensures you use less product per treatment compared to diluted or low-fume alternatives.
Total Alkalinity Control
This is what pool techs reach for when they need to aggressively lower total alkalinity levels in stubborn water to prevent scale.
Professional Grade Versatility
While primarily a pool balancer, it is also rated for brick and mortar cleanup and professional acid washes on plaster pool finishes.
Product Details
HYDROGEN CHLORIDE 31.45%
12-16 fl oz per 10,000 gallons to lower pH by approximately 0.2.
Compatibility
- Do not mix with chlorine or any other chemicals
- Keep away from metal surfaces to prevent corrosion

When To Use This
Pro Tip
Always add acid to water, never water to acid. When pouring into the pool, pour slowly in front of a return jet with the pump running to ensure immediate mixing and prevent the acid from settling on the floor. In regions with high-alkalinity fill water, such as the Southwest, keeping this 1 Gallon bottle on hand is essential for preventing scale formation on salt cells.
Common Questions & Instructions
How much muriatic acid do I add to my 10,000 gallon pool?
To lower pH by approximately 0.2 units in a 10,000-gallon pool, you typically start with 12 to 16 fl oz of this 31.45% concentration, though total alkalinity levels will dictate the exact requirement.
Is muriatic acid better than dry acid for pool maintenance?
In our experience, muriatic acid is more cost-effective and faster-acting for large adjustments, though it requires more careful handling and transport than sodium bisulfate (dry acid).
Can I swim immediately after adding muriatic acid?
We recommend waiting at least 30 to 60 minutes with the pump running to ensure the acid is fully dispersed and the pH has stabilized before re-entering the water.
