HASA Muratic Acid - 2 Gallon Case
Product Overview
What pool techs reach for when high pH or alkalinity threatens water clarity and equipment longevity.
This 2 Gallon case of HASA muriatic acid contains a professional-strength 31.45% Hydrochloric Acid solution, the standard specification for effective water balancing. While the master packaging may reference a 4 GALLON net weight, this case provides two 1-gallon bottles designed for precise dosing in residential and commercial pools. It reliably handles stubborn pH spikes and is essential for maintaining the ideal saturation index to prevent scale formation.
Benefits & What Makes It Different
31.45% Hydrochloric Acid
This high-concentration formula is more cost-effective than half-strength retail versions, requiring less product to achieve the same reduction in pH and alkalinity.
Precise Alkalinity Reduction
Adding 1.25 pints per 10,000 gallons will lower alkalinity by 10ppm, providing a predictable way to manage water chemistry without the guesswork of dry acid alternatives.
Versatile Maintenance Tool
Beyond balancing, this acid is the proven choice for cleaning salt cells and removing calcium scale from concrete surfaces, ensuring your equipment runs efficiently.

When To Use This
Pro Tip
In hard water areas like Central Texas or Arizona, high source-water alkalinity makes HASA muriatic acid a weekly necessity to prevent scale from clogging filters and salt cells.
Common Questions & Instructions
How much HASA muriatic acid do I need to lower my pool's alkalinity?
To lower total alkalinity by 10ppm in a 10,000 gallons pool, you should add approximately 1.25 pints of 31.45% Hydrochloric Acid. Always test your water first and add the acid in small increments to avoid over-correcting your pH levels.
Can I use HASA muriatic acid to clean my salt chlorine generator cell?
Yes, this 31.45% muriatic acid is what pool techs reach for when cleaning salt cells; typically, a 4:1 water-to-acid ratio is used to dissolve calcium buildup without damaging the plates.
Is it safe to swim immediately after adding muriatic acid to the pool?
We recommend waiting at least 30 to 60 minutes with the circulation system running after adding acid to ensure it is thoroughly dispersed. Swimming in concentrated pockets of acid can cause skin and eye irritation.
