It has happened to all of us, walking into a friends or neighbours home and the pool has almost blinded you. The question that comes to mind; why is that pool so sparkling clean and bright? The true success of a stunning pool is the PH balance. Pure water is a neutral PH 7 at (25 °C), being neither an acid nor a base, so waters PH is a measure of its total acid-alkalinity balance and proportion. The recommend PH of a swimming pool is between 7.2 and 7.8. , so paying attention to your pools PH is essential to maintaining ideal swimming conditions.

The water might still appear clear even though your PH balance is out, so it important to test and keep an eye on pH even though your water might look fine. Testing is necessary to keep your pool clean, safe, and prevent damage to your pool equipment.


If your swimming pool PH is too high:

In other words to acidic your reading will be below 7 in other words zero to 6, zero indicating extreme acidity. To increase your swimming pools pH add soda ash (sodium carbonate) Pre-dissolving the soda ash in a container with clean, warm water. Whilst the pump is running pour the solution all around the pool parameter to allow for re-circulation. Check your levels again after 2 hours, if your readings are still below 7 repeat the process.


If your swimming pool PH is too low:

In other words to alkaline your reading will be above 7 in other words 8 to 14, fourteen indicating extreme alkalinity. To decrease swimming pool pH add Hydrochloric Acid. Whilst running the pump in normal position, pour the acid around the parameter of the pool to allow for recirculation or add the acid by pouring into the weir. Check your levels again after 2 hours, if your readings are still below 7 repeat the process.

By making sure your PH is correct in your swimming pool ensures comfortable swimming, no more red eyes and skin irritations, longer lasting pool equipment and surfaces. Water that does not have the optimal PH will cause chemical reactions that renders your chlorine ineffective and consumption increases, also increasing the chance that you may have to give your pool a shock treatment. The general rule of thumb is to test your swimming pools PH at least once a week, however the more you swim the more your should test. While you have the test kit out, check your pools chlorine as well, you will end up with one of those bright sparkling pools that your neighbours envy.
