Stable PH levels are the foundation of a clean pool. 

If your PH is incorrect then your swimming pool water will become unhygienic making it not safe to swim in and can also hurt the eyes and skin of swimmers. It is important to test and correct your swimming pools PH level. Testing your pool's pH level is as simple as dipping a strip of paper in the water. 

Pool water should be tested regularly to ensure it remains clean and hygienic. The pH scale, a measurement of acidity or alkalinity that runs from 0 to 14. A reading between 7.2 and 7.8 is ideal. this is the best range for swimmers and helps sanitize water efficiently.

You can monitor your pool's pH level with a testing kit. Most homeowners have either reagent kits or test-strips. Reagent kits are simple to use. You take a sample of pool water, then add liquids or tablets to it. The water changes colour, indicating its chemical balance. Test-strips work differently. In that you submerge them in the pool for a few seconds, chemicals they contain cause them to change colour you then match colour of the strip to a colour chart to determine the pool's pH level. You use the results of these test to gauge what kind and how much of the chemicals your pool need. You can also take a sample of water to your local pool store who can run a comprehensive water analysis and provide advice on the chemicals required to correct the water composition.

Once the pool's water composition is correct your pool will appear much cleaner, less cloudy and have less algae growth taking the pressure off your filter and pool cleaner.
