WATER LEVELS - SALT - EQUIPMENT -  PLUMBING - POOL MAINTENANCE

Why does PH Matter?

You should aim for pH levels between 7 and 7.6.



A pH reading tells us whether the pool water is acidic or alkaline and is the single most important factor to consider when balancing your pool water chemistry. Ph levels help to maximise the effectiveness of both the chemicals and circulation.


The ideal pH level, and maintaining your pH level will most certainly differ depending on what sort of substrate your pool has (your pH will differ depending on if your pool is fully tiled, pebblecreted, marblesheen, epoxy painted, vinyl lined etc)


Hint: Pebblecrete pools are more susceptible to pH swings.


There are many reasons why it's important to keep your PH levels correct, Here are just a few:

  • A high PH can cause skin rashes, cloudy water and scaling on pool equipment - Scaling inside pipes can build up, which then restricts water flow, which puts extra stress on your circulation system, which ultimately results in extra costs (damaged equipment)

  • A Low pH can cause itching, etching and deterioration of the plaster, grout, stone & concrete and even cause a vinyl liner to become brittle. Low pH ultimately damages your substrate over time.

  • Certain chemicals require a specific pH level to maximise their effectiveness (ie: flocculants provide best results when the pH is approx 5.5 as high pH levels will often cause coagulated particles to redisperse).

  • pH variations change the effectiveness of your chlorine's ability to sanitise the pool.


What causes my pool pH level to drop?

Rain water is naturally slightly acidic, with a pH of about 5.0, so storms and excessive rain can lower your pool's pH level. As can overuse or the incorrect use of pool chemicals. After a heavy rainstorm, or a big pool party, we recommend raising your pH to neutralize the effect of the extra rainwater and use.


How do I raise the pH level in my pool

To raise the pH levels in your pool you can add soda ash (AKA buffer or sodium bicarbonate)


How do I lower the pH level in my pool

You can either use HCL (hydrochloric acid) or a more diluted form, called Muriatic acid.

Warning : Always dilute acid before adding to your pool water and always add acid to water, and not water to acid to minimise splashing the acid onto you. Be mindful to always use protective eyewear.



DID YOU KNOW : Algae, calcium and sudden heat can raise the pH level.
