How to Select the Right Size Pool Chlorinator.
Here’s how to find the right chlorinator for your pool size, to ensure optimal chlorine production and water quality…

Size Matters.
Choosing the right size chlorinator for your pool is crucial for maintaining proper sanitation. If the chlorinator is too small, it won’t produce enough chlorine to keep your pool clean.
To determine the right size chlorinator, consider the size of your pool. Most chlorinators are rated by the amount of water they can handle, usually measured in gallons. Be sure to select a model that matches or slightly exceeds your pool’s water volume.
Measuring Your Pool.
To calculate how many litres are in your pool simply multiply the length by the width and then the average depth (depth at the deep end plus depth at the shallow end divided by 2).
Even if your pool is not rectangular in shape, this is still a good way to measure it, as it is always a good idea to overestimate the pool size anyway, so the chlorinator you choose does not have to work too hard to maintain it. Therefore any curves in the pool can be ignored.
Pool Usage is Important.
Pool usage is another factor to consider. If you swim frequently or host pool parties, you’ll need a chlorinator with a higher output to keep up with the increased demand for chlorine.
Don’t be tempted to buy a chlorinator that is under rated for your pool size if you don’t use it much though, as it will need to run for a lot longer to maintain chlorine levels in your pool and thus cost you a lot more in the long run due to electricity usage.

Overestimate to Allow for Anomalies.
Other factors that affect chlorinator sizing include location and the presence of features like waterfalls or spas. These can impact water flow and the chlorinator’s ability to maintain proper chlorine levels. This is because pools with no shade lose chlorine faster, due to the heat of the sun causing it to activate, and the increased water circulation of waterfalls and spas can lead to faster chlorine breakdown.
As with unusually shaped pools, it’s always best to overestimate which size chlorinator to buy than underestimate and have it working overtime. Basically, if you calculate your pool volume to be very close to the maximum recommended size of one model of chlorinator, then go for the next size up, just to be sure. If your measurements are well within the recommended range however, then you are going to be totally fine. Remember to also maintain your pool chlorinator regularly to ensure optimal performance and longevity.
