pH Control of Swimming Pools

One of the key areas of swimming pool management is pH control. The preferred choice is carbon dioxide which provides a clean, safe and simple alternative to using mineral acids.

Carbon dioxide is used in swimming pools to optimise the pH level, ensuring it is neither too acidic or alkaline.

When dissolved in water, carbon dioxide reacts to form a carbonic acid and other reactive compounds. These react with alkaline solutions to reduce the pH to a more desired level.

Advantages of using Carbon Dioxide over Mineral Acids for pH Control

Carbon dioxide forms a natural carbonate buffer stabilising pH levels (the risk of over acidification is avoided) - eliminating the need to add carbonates to alkaline water.
The risk of accidentally generating Chlorine gas is virtually eliminated.
There is no handling of potentially dangerous / harmful chemicals by pool operatives - there is no need to mix, decant pour or pump chemicals.
Totally dissolved solid levels are improved.
Corrosion to the operating equipment is significantly reduced.
Efficiency and flock filtration are improved.
