PoolM8 is the ideal App for every discerning pool and spa owner.

As experts in pool and spa water analysis, the Lovibond® team has always been keen to educate on the importance of balanced water, otherwise known as the ‘Langelier Index’.

When water is in balance, it is said to be neither corrosive nor scale-forming. In other words, it will neither dissolve an existing layer of scale nor will it deposit a layer of calcium scale. Unbalanced water can aggressively eat away at the pool’s infrastructure.

The Langelier Saturation Index (sometimes also known as the Langelier Stability Index) was developed in the 1930’s to determine a formula resulting in a single calculated number which is used to notify how much calcium is in the water. The golden result of just above “0” is said to mean the water is ‘in balance’.

The Index is very reliable, using various ‘parameters’ that can have an effect on the water balance and each is given a factor to give an Index value. Those parameters are:
Total Alkalinity
Calcium Hardness
Total Dissolved Solids

Each of these parameters has an effect on each other proven by a formula (please visit www.lovibondwater.com for further information). The formula, however, can be complex to calculate – often leading to errors in determining the exact value.

The Lovibond® team has now solved this problem and is happy to share it with you. Simply type in your results to determine the balance of your pool water!
