Castle Hot Tubs

5kg Total Alkalinity Raiser



Blue Horizons Total Alkalinity Raiser  - TA is a measurement of the waters ability to resist pH change.
If the TA is low then the pH can fluctuate. This can make it difficult to control and maintain at the ideal level.
If the total alkalinity is high then the pH can be difficult to change and will keep rising. A high TA can also lead to the formation of a bicarbonate scale on pool surfaces, within pipework and in plant room equipment.

Instructions for use
Pre-dissolve the product in a clean plastic container at a maximum rate of 100g of product per 2.2 gallons (10lts) of clean water.
Stir well to ensure product is fully dissolved.
Add the resulting solution to the pool whilst the pump(s) are turned on, preferably near to the water inlets to aid distribution.
