Puri Tech Chemicals pH Minus 20lb Resealable Bag for Swimming Pools & Spas pH Decreaser Down Reducer 100% Sodium Bisulfate Lowers Total Alkalinity & pH

ACTIVE INGREDIENT:
Sodium Bisulfate - 100%

PRODUCT DESCRIPTION:
pH Minus lowers pH levels and the total alkalinity of swimming pools. The ideal pH range is 7.4 - 7.6. A pH in this range will allow your sanitizer to work effectively, and reduces corrosion, eye irritations, and skin dryness.

DIRECTIONS FOR USE:
1. Determine the amount needed using the chart below.
2. Fill a gallon plastic bucket with water.
3. Add the proper amount of pH minus and mix with a wooden spoon or plastic utensil until fully dissolved.

3. DO NOT add more than 32 ounces of product per 10,000 gallons at one time.
4. After 4 hours, water should be retested and additional product can be added.

HOW TO LOWER TOTAL ALKALINITY:
Always adjust total alkalinity first, keeping between ideal range of 80 - 150 ppm.
If total alkalinity is high: Add 2 lbs for every 10,000 gallons of pool water to lower 10 ppm.
Keep circulation pump running and add product at deepest part of pool. Wait 4 hours before adding more product.
