Muriatic Acid 31.45% hydrochloric acid Refillable

HASA Muriatic Acid is a strong inorganic acid, also known as hydrochloric acid. It has a wide variety of industrial uses but around swimming pools and hot tubs, it is most commonly used to lower pH and alkalinity.

DIRECTIONS FOR USE:
This product reduces pH to minimize scale. Use as required to maintain pH between 7.2-7.6. Use a
reliable test kit. Do not overdose. When in doubt use less muriatic acid. To reduce pH, add one quart
HASA MURIATIC ACID per 20,000 gallons of pool water per 24 hours. Add acid cautiously at deep
end and at least one foot from pool wall. Pour slowly over as large an area as possible. The
recirculation system (filter and pump) must be running while adding HASA MURIATIC ACID and for at
least one (1) hour after the addition. Repeat as necessary at 24 hour intervals.
