Importance of a Balanced Pool

Postby belitakin123 » Thu 24 Aug, 2017 06:17

One of the most important steps of swimming pool maintenance is water balance. Generally, understanding water balance can also be one of the most confusing processes of pool maintenance. Because of its complexity, some new pool owners may not know everything they have to do to keep their pool water safe, comfortable and corrosion free.
Below are a few of the reasons why having a balanced swimming pool is so important:
Safety
If you are using either a salt based pool producing chlorine or a chlorine based tablet pool, then your pH needs to be correct. If pool water is not balanced correctly then the chlorine sanitizer won't be working at full strength killing germs and bacteria.
Comfortable
Your water balance needs to be correct or it will affect your skin and eyes. The pH should be neither too acidic nor basic in order to feel comfortable.
Corrosion
An imbalanced pool can be corrosive to the liner, ladders and hand rail and other equipment such as the pump.
What is entailed in Water Balance?
Total Alkalinity
Total alkalinity refers to how much alkaline is in the water. TA and pH go hand-in-hand. High alkaline water leads to high pH. Low alkaline water leads to low pH. That the average swimming pool should have an alkalinity reading of 100 ppm.

Swimming Pool Water pH Levels
Keeping your pH levels within the proper range is important for keeping your equipment and pool finish intact. pH refers to the acidity or baseness of your pool water. A proper pH level is around 7.4 to 7.6 on a pH test kit's numeric scale. 0 to 7 reflects a low or acidic pH. 8 to 14 means the pool has a base pH level. Your chlorine will dissolve quicker with a low pH level. High pH levels make chlorine inactive.
Calcium Hardness
The right amount of calcium in your pool is essential. If there is too little, your plaster can erode. Too much calcium can make your water could become cloudy, scale could form and stains might start. 200 to 400 ppm is the general range for calcium hardness, while 300 ppm is ideal for the average pool.

Although a lot of above is correct some are not

A pH of 7 is neutral below is acidic and above alkaline. 7.4 to 7.6 is ideal but no way should it raise above 8-14
What makes chlorine ineffective is your cyanuric acid level with relation to the Chlorine / CYA Chart against the recommended Pool Levels
CYA is introduced through pucks, tablets and granules
For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm.
For every 10 ppm FC added by Cal-Hypo, it also increases Calcium Hardness (CH) by at least 7 ppm
With relation to calcium hardness, plaster pools require calcium to prevent the calcium being taken fron the plaster whereas vinyl and fibreglass don't require any at all
