SpaChoice 1-Quart Premium pH Increaser for Hot Tubs – Made in USA

Meet SpaChoice 1-Quart Premium pH Increaser, a carefully formulated liquid designed to bring spa water up to the ideal pH range. When water skews toward the acidic side, the product acts as a quick-acting solution to restore balance, helping water feel comfortable and clear.

Key benefits and compatibility: this product raises pH in spa water and is compatible with common sanitizers such as bromine, chlorine, and biguanide. By maintaining a stable pH, you may support better sanitizer performance and reduce eye or skin irritation for many spa users.

What you can expect in real-life use

With regular testing and measured dosing, you can keep your hot tub water in the target range of 7.2–7.8 pH and 80–140 ppm total alkalinity. The 1-ounce-per-100-gallon dosing makes it straightforward to adjust for different tub sizes, from small to large spas.

• This product should be used if pH is below 7.2.
• Add 1 ounce of this product for every 100 gallons of spa water.
• Retest water after 30 minutes and adjust as needed.
• Continue dosing until pH and total alkalinity are in the recommended range (7.2–7.8 and 80–140 ppm).

How to use (quick guide):

• Turn on the spa air blower, jets, or filter system to mix the water.
• Pour the measured amount of pH increaser into the water.
• Re-test after 30 minutes and repeat if necessary.
• Keep a routine test schedule to maintain balanced water chemistry.

Designed and produced in the United States, SpaChoice emphasizes quality and consistency, helping you maintain comfortable, clear spa water without guesswork.

Always read and follow the product label. Dose to the label rate for your actual water volume, never mix pool chemicals together, and store them dry, sealed and away from children and pets.
