To lower pool pH, add muriatic acid (liquid) or sodium bisulfate (dry acid) to your pool water. Use 1 quart of muriatic acid per 10,000 gallons to lower pH by 0.2 units, testing and adjusting gradually.
Yes, pool pH can definitely be too high. When pH exceeds 7.8, it causes cloudy water, reduced chlorine effectiveness, equipment damage, and skin/eye irritation. Lower it gradually with muriatic acid or sodium bisulfate.
To lower pool pH, add muriatic acid (1 pint per 10,000 gallons to drop pH by 0.2) or sodium bisulfate following package directions. Test first, add chemicals to deep end with pump running, wait 4 hours, then retest.
To lower pool alkalinity, add muriatic acid or sodium bisulfate (dry acid) to your pool water. Use 1 quart of muriatic acid per 10,000 gallons to lower alkalinity by approximately 10 ppm.
To lower pool alkalinity, add muriatic acid or sodium bisulfate (dry acid) to the deep end with the pump running. Use 1.3 lbs of muriatic acid per 10,000 gallons to lower alkalinity by 10 ppm.
