Symptoms of low pH in hot tub water include skin and eye irritation, excessive sanitizer use and , more seriously, corrosion of the pumps and heater and pitting or etching on the spa shell surface. Therefore, if the pH of your water is below 7.2 it is important to raise it using pH Increaser.
Dose : 11g per 1000 litres of spa water.
Pre-dissolve the product in a clean plastic container at a maximum rate of 11g per litre of warm water. Stir well to ensure that the product is fully dissolved and add the solution to the spas with the pumps running to ensure even distribution.
After a minimum of 30 minutes re-check the pH level and repeat if necessary until the required pH is reached. A number of treatments may be necessary.
NB If you are unable to maintain an appropriate pH level in your tub the most likely cause is that the the Total Alkalinity is too low. Always correct the Total Alkalinity balance before you attempt to balance the pH.
When water molecules are ionized, they produce hydrogen ions (H+) and hydroxyl (OH-) ions, which carry an electrical charge. These ions in the water determine whether the water is acidic (excess H+) or alkaline (excess OH-). The term "pH" refers to thehydrogen-ion concentration and is defined as the logarithm of the reciprocal of the hydrogen-ion concentration. The scale ranges from 0 to 14 with a pH of 7 being neutral. Higher pH values denote alkalinity, lower pH values acidity. Because it is a logarithmic scale, a solution at pH 5 is 10 times more acidic than a solution at pH 6, 100 times more acidic than a solution at pH 7, and 1,000 times more acidic than a solution at pH 8.
