pH is a measure of how acidic or how basic water is. The pH range goes from 0 to 14, with 7 being neutral. A pH of less than 7 indicates acidity, a pH of greater than 7 indicates a base. The pH of water is a very important measurement of the water quality of your hot tub. A high pH level in a pool or hot tub water can cause limescale build up, which can damage working parts including pumps, heaters and seals.

A powdered product for increasing the pH of swimming pool water

Key Features
o Easy-to-dose powder for increasing pH
o Part of the B.O.A.S.T. System

Ideal pH Range: 7.2 – 7.6
The ideal pH level is between 7.2 – 7.6, promoting bather comfort, optimal
chemical efficiency and protection of pool plant equipment. Test the pH of your
pool water and if it is below 7.2, use Blue Horizons pH Plus to raise it.

Application Instructions

1. Pre-dissolve the product in a clean plastic container at a maximum rate of
100g of product per 2.2 gallons (10ltrs) of clean warm water. Stir well to
ensure the product is fully dissolved. Carefully add the resulting solution to
the pool whilst the pump(s) are turned “on”, preferably near to the water
inlets to aid distribution.
2. After a minimum of 8 hours, recheck the pH level and if necessary, repeat
the treatment until the ideal pH level is established.
