Pro Tip
In hard water areas where evaporation is high, alkalinity tends to creep up; using this acid regularly prevents scale from forming on your salt cell or heater. Always add acid to water, never water to acid, to prevent dangerous splashing.
Common Questions & Instructions
How much HASA muriatic acid do I need to lower my pool's alkalinity?
To lower Total Alkalinity by 10ppm, you typically need 1.25 pints of this 31.45% muriatic acid per 10,000 gallons of water, though actual results may vary based on other water factors.
Can I use HASA muriatic acid to clean pool tiles or concrete?
Yes, this Hydrochloric Acid is effective for removing scale from tiles and cleaning concrete, but it must be diluted properly with a minimum ratio of 10:1 to prevent damage to surfaces.
How long should I wait to swim after adding muriatic acid?
We recommend waiting at least 30 to 60 minutes with the circulation system running to ensure the acid is fully dispersed and the pH has stabilized before entering the water.
