Total alkalinity measures all alkaline substances (iconic compounds) that are dissolved in your pool water.
These compounds include bicarbonates, carbonates and hydroxides, along with a few others such as cyanurate alkalinity.
When alkalinity levels are in check, it helps to stop rapid pH fluctuations that can lead to water problems.
pH is an abbreviation for “potential hydrogen” and is a measurement of water acidity. The pH scale ranges from 0 to 14, where 7 is neutral. Anything above 7 is alkaline and everything below is acidic.
In swimming pools ideal range for pH levels is between 7.2 to 7.8. Recommended pH for concrete or vinyl liner pools is 7.4. The optimal for fibreglass pools is 7.2.
There are a few clear signs when your pool’s alkalinity is out of balance. If it’s too low, the water can become corrosive, irritating swimmers’ skin and eyes and damaging pool surfaces and equipment.
If alkalinity is too high, it can lead to calcium scaling or cloudy deposits forming because of pH and calcium interactions. This can also make the water appear cloudy and difficult to keep the water clean.
Keeping an eye on these symptoms will help you to maintain a healthy pool.
There are several different factors always influencing alkalinity levels in your pool.
pH Levels
The relationship between alkalinity and pH levels in a pool is intertwined.
Water Source
The water source for the pool significantly impacts alkalinity levels.
higher alkalinity than municipal water supplies.
Chemical Additions
Adding chemicals to adjust your pool’s pH will affect its alkalinity.
Environmental Factors
Environmental elements like rainfall, falling debris and organic matter can alter your pool’s alkalinity levels.
Pool Usage
The frequency of pool use can impact the water’s alkalinity.
Add chemicals according to manufacturer instruction for dosage and application.
Alkalinity target levels are 80-120 ppm.
Increase Total Alkalinity Levels
There are various products available to increase alkalinity such as Buffer, Alkalinity Increaser or Alkalinity Up.
They all contain sodium bicarbonate, commonly known as bicarbonate of soda or baking soda.
Decrease Total Alkalinity Levels
Hydrochloric Acid, Muriatic Acid, or Dry Acid is used to lower alkalinity levels in your pool.
Dry acid also known as pH Down or pH Minus is made from sodium bisulphate.
It’s safer to use and less corrosive than hydrochloric or muriatic acid, but still must be handled with care.
