Alkalinity – 2 things to remember

Alkalinity… a hard word to type for some, a hard word to say over and over 5 times… and it makes life hard when there’s too much in your pool water.

We all know about pH levels and how keeping them balanced is important in keeping your pool in tip-top shape (generally keeping a pH level somewhere between 7-8).

1. What part does alkalinity play in ‘healthy’ pool?

Alkalinity can help to neutralize acidic pollution (such as in pools, rainwater and other water streams). Using products with alkaline properties can help to buffer against acidity. Hydrologists use alkalinity to describe ‘temporary hardness’, which is helpful when remembering what it does, making it hard for acidity to take over. That’s obviously not very scientific but a helpful way to remember it nonetheless. It also brings us to the next point.

2. What happens when the alkaline levels are too high?


It doesn’t happen that often, but when it does happen it can be hard to fix. Water can become harder to see through (cloudy) and scale can build up on the pool’s surfaces which is hard to remove.

Making sure the acidity and alkalinity are balanced will make sure you are getting the positive properties needed for a clean pool from both ends of the pH scale, without the damaging properties.
