Blue Horizons pH Plus is a highly effective, powdered chemical solution designed for pool and spa owners who need to raise their water's pH levels to the ideal 7.2 to 7.6 range. It is an essential treatment for ensuring bather comfort, maximizing the efficiency of your other pool chemicals, and preventing the corrosion of expensive pool equipment. While it provides a reliable way to balance water chemistry, users should note that the powder must be pre-dissolved before application and requires an 8-hour waiting period between doses to see accurate, stable results.

It is recommended to test your pool water at least twice a week, or more frequently during heavy use or after rain.
No, you must pre-dissolve the powder in a bucket of warm water first to ensure it is fully integrated into the pool water without damaging the pump or heater.
The ideal pH range for swimming pools and spas is between 7.2 and 7.6.
pH Plus does not directly increase chlorine, but it makes your chlorine much more effective by keeping the water chemistry in the correct range.
It is best practice to wait for the pump to circulate the water for at least one full cycle (usually a few hours) before swimming.
Check your total alkalinity levels first; if alkalinity is too low, the pH will be unstable and difficult to raise. Ensure you are waiting the full 8 hours before retesting.
The product has been exposed to moisture. Store in a strictly dry environment; ensure the container is sealed airtight after every use.
This product is compatible with all standard pool and spa filtration systems. When storing the product, ensure it is kept in a cool, dry, and well-ventilated area, away from direct sunlight and other chemicals. Always keep the lid tightly closed to prevent moisture from clumping the powder. When handling, wear protective gloves and eye protection to prevent irritation, and avoid breathing in any dust generated while measuring or mixing the product.
