How to test and balance total alkalinity

Are you sitting there thinking, “How do I test and balance the total alkalinity of my swimming pool?”

At Pool Broker we have the best experts when it comes to testing and balancing water.

Did you know that this is one of the first things you should test and balance? The reason this needs to be tested and balance first is because Alkalinity is the foundation for preventing rapid changes on your pools pH levels. Ultimately, if the Alkalinity in your pool is within range, your pH levels will remain stabilised. What is the ideal alkalinity range? The ideal Alkalinity range should be between 80 ppm and 120 ppm.


To increase levels you need to add the required Sodium Bicarbonate to bring the levels back in balance. This is also referred to as Alkalinity Increaser or pH buffer.


To decrease levels simply add the required acid (liquid or dry) to your pool (deep end). You should always break your acid dosage into 3 parts, and dose the pool with each part across 2 – 3 days.

You should always refer to your chemical packaging for dosage amounts, and safe handling. For your safety, never premix different chemicals together before adding them to the water. It is recommended that dry chemicals be mixed into the water in dosages of about 500g to 1kg. Be sure to follow the manufacturers instructions found on their packaging.
