Total Alkalinity – The Buffer for PH
In many ways Total Alkalinity it similar to pH and how it runs from acidic to alkaline. Consider pH like a thermometer on a furnace thermostat.
How to Balance PH
The ‘Water Balance Triad’ starts with the pH of your pool. The water used here should have a pH between 7.2 and 7.8. Ideally, your pool reading would be 7.4 which is the average pH of the human body. This reduces the risk of both skin and eye irritation.
Water Balance – Turning the Pool Triad
So, you’ve filled your pool, added in the sanitiser and brought your pH, Total Alkalinity and Hardness levels to the ideal reading. Your pool is now perfectly balanced. However, as soon as you open the lid for use, this all goes down hill.
Chlorine – The Most Popular Biocide
In the second part of our SpaChem ™ FAQ series, we will discuss chlorine – the most popular water treatment biocide available.
Chlorine is an excellent sanitiser which has both advantages and disadvantages when it comes to pool, hot tub and spa use. Below we have listed some of the key factors to consider:
Calcium Hardness – The Solubility Controller
So far, we have discussed both pH, Total Alkalinity and how the two interact. This leads us on to our next subject – Calcium Hardness and it’s part in Water Balance.
All water has an intrinsic hardness to it. This refers to the amount of minerals, such as calcium and magnesium, which can be found dissolved into it. Here in the UK, you can find all levels of hardness from very soft through to very hard. Check with your utility supplier to find out the level of water hardness you have in your area and be aware that it can vary from postcode to postcode.
