Muriatic Acid: Balance/Reduce pH and Total Alkalinity(TA)
Publisher: The Summer Pools
Details: Muriatic Acid or Hydrochloric Acid solution contains Hydrogen Chloride and is therefore a strong acid solution. Balancing pH and Total Alkalinity is quite a task (TA) when they get out of recommended range of 7.2 - 7.8 for pH, and 80 - 120ppm for Alkalinity. Muriatic acid is the best chemical to lower both pH and TA when they get off the range.
Muriatic Acid Dosage: 0.8 qts reduces TA by 10ppm in a 10,000 gallons pool.
