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.
