Why Hot Tub pH Increaser? Did you know that the water in your spa should be maintained at a pH of 7.2 to 7.8 and total alkalinity from 80 to 140 ppm? Using a pH up for hot tub spa will help you maintain your hot tub chemistry effectively.

pH Up For Hot Tub Spa - Our pH increaser for hot tub will help you maintain your hot tub chemistry balance. If your spa's pH measure is below its range, it is essential to use a hot tub pH booster to treat cloudy tub, scale build-up, and more.

Spa pH Increaser For Hot Tub - When your hot tub pH is not at an ideal level, it indicates that your hot tub water is too acidic, and your sanitizer will be less effective. Using a pH increaser will also help you raise the total alkalinity level.

pH BUFFER - Helps prevent PH bounce, "locks" pH in the ideal range by neutralizing acids like acid rain. It boosts up the effectiveness of your pool water cleaner and is user friendly. Add 1 Lb per 8,000 gallons to raise 10 ppm. Maintain total alkalinity to 80 to 120 ppm.

ALKALINITY CONTROL - Alkalinity Control is used when pH levels fluctuate widely over a short period of time. A low total alkaline reading is also indicative of corrosive pool water, a blue or green cast to the water and difficulty in holding chlorine residuals. Low alkalinity can cause equipment and plaster damage. If the alkalinity is too low or too high, the pH of the pool water will be difficult to maintain in the proper range. This product is used to increase the total alkalinity in swimming

WATER CHEMISTRY - One of the most important aspects of proper swimming pool care involves the maintenance of balanced water chemistry. When swimming pool chemicals are not in balance, swimmers can be at risk of contracting illnesses and suffering from skin irritation, the water can turn dull and cloudy, and pool equipment and surfaces can become damaged.

Use when total alk. drops below 80 ppm.
