Description
Product Overview
Clorox Pool Spa pH Up is a professionally formulated granular pool balancer that targets low pH conditions, a common challenge for pool owners seeking clear, comfortable water. The product delivers a precise amount of sodium carbonate, which gently raises the pH level without causing sudden spikes that could destabilize other chemical balances. Each 4‑lb (64 oz) package contains enough active ingredient to treat medium‑sized residential pools, typically ranging from 10,000 to 20,000 gallons, depending on the degree of pH deficiency. The granular form dissolves quickly when added to circulating water, ensuring uniform distribution and rapid correction of acidity. This formulation is compatible with chlorine‑based sanitizers, bromine systems, and salt‑water generators, allowing seamless integration into existing maintenance routines.
The product is manufactured by Clorox® Pool&Spa™, a trusted name in water care that adheres to rigorous quality standards and third‑party testing protocols. The packaging includes clear dosage instructions, safety warnings, and a QR code that links to the Clorox Pool App, where users can log water parameters, receive personalized dosage recommendations, and set reminders for future treatments. The 4‑lb container is designed for easy storage, featuring a resealable lid that prevents moisture ingress and maintains product potency over time. The product dimensions of 4.4 × 9 × 10.5 inches make it convenient to keep in a garage, pool house, or utility closet.

Usage
Clorox Pool Spa pH Up is intended for use in residential swimming pools, hot tubs, and spa environments where the pH level has fallen below the optimal range of 7.2 to 7.6. Low pH can cause water to become acidic, leading to eye irritation, dry skin, and accelerated corrosion of metal components such as ladders, pumps, and heaters. To use the product, ensure the pool circulation system is running, then slowly sprinkle the recommended amount of granules across the water surface. The granules will dissolve within minutes, and the pH level should begin to rise steadily. It is advisable to retest the water after 4 to 6 hours using a reliable test kit or the Clorox Pool App to confirm that the desired pH range has been achieved.
For larger pools or situations where the pH is significantly low, multiple doses may be required. In such cases, split the total dosage into two or three smaller applications spaced several hours apart to avoid over‑correction. The product works well in conjunction with other balancing chemicals, such as alkalinity increasers and calcium hardness adjusters, allowing pool owners to maintain a comprehensive water chemistry program. When treating hot tubs or spas, use a reduced dosage because of the smaller water volume, and always follow the manufacturer’s guidance to prevent foaming or excessive alkalinity.
Safety precautions include wearing protective gloves and eye protection during handling, storing the product out of reach of children and pets, and keeping the container tightly sealed when not in use. The granules are non‑toxic but can cause irritation if they come into direct contact with skin or eyes. In the event of accidental exposure, rinse the affected area with plenty of water and seek medical attention if irritation persists. Proper disposal of any leftover product should follow local hazardous waste regulations, although the material is generally considered safe for household waste when the container is empty.

FAQ
How much pH Up should I add to a 15,000‑gallon pool?
The exact amount depends on the current pH level and the desired increase. As a general guideline, adding 1 lb of Clorox Pool Spa pH Up to a 15,000‑gallon pool will raise the pH by approximately 0.2 units. It is recommended to test the water, add the calculated dose, retest after 4–6 hours, and adjust if necessary.
Can I use pH Up together with a chlorine shock treatment?
Yes. The granular pH Up does not interfere with chlorine shock. In fact, maintaining the proper pH range helps chlorine work more efficiently. Apply the pH Up first, allow the water to circulate, then perform the shock treatment according to the manufacturer’s instructions.
Is the product safe for children and pets?
When used as directed, the product is safe for the pool environment. However, the granules can cause irritation if they come into direct contact with skin or eyes, so it is important to handle the product with gloves and keep it out of reach of children and pets. Rinse any exposed skin thoroughly with water.
What should I do if the pH rises too high after treatment?
If the pH exceeds the recommended range (above 7.6), you can lower it using a pH decreaser such as sodium bisulfate or muriatic acid. Add the decreaser slowly while the pump is running, retest the water after a few hours, and repeat if necessary until the pH returns to the optimal range.
Does the product affect total alkalinity?
Clorox Pool Spa pH Up is formulated to have a minimal impact on total alkalinity. While any pH adjustment can cause a slight change, the effect is typically negligible. If you notice a significant shift, you may need to balance alkalinity separately using an appropriate alkalinity increaser.
