Product Information

Poolife pH Minus is a white, granular form of sodium bisulfate (dry acid). Poolife pH Minus is equally effective at lowering your pool’s pH levels and lowering Total Alkalinity (TA). But it depends on how the product is applied.

• Use Poolife pH Minus to lower pH
• While water is circulating, broadcast widely over the deep end of the pool.
• If you would like to pre-dissolve and add pH Minus as a liquid, add the liquid as you walk around the sides of the pool.

Dosage/Frequency

To Lower pH:

• Try to keep your pH levels between 7.2 – 7.8
• Use this product if pH goes above 7.8
• Proper dosages will vary
• The proper dosage is determined by your current pH
• First, test current pH. Then refer to product label for proper dosage to adjust pH

To Lower Total Alkalinity:

• Add the product in one localized area at the deepest end of the pool: this will create a localized pocket of low pH, which will lower your total alkalinity
• Total alkalinity (TA) should be in the range of 80 – 120 ppm
• Adding 2 lbs. per 10,000 will lower TA by 10 ppm
• Do not exceed 2 lbs. per 10,000 gallons per day: if additional adjustment is needed, add the following day

*Important* Remember, do not broadcast. The key is to add the acid in one isolated area
