The Top 3 Things To Check on Your Salt Water Chlorinator

Common salt water chlorinator problemsIs your salt chlorinator not producing chlorine? The majority of Australian domestic swimming pools are now salt water chlorinated and we’re often asked about common salt water chlorinator problems and how to make sure your chlorinator is working efficiently to keep your pool healthy and sanitised throughout the swimming season.

There are 3 key things you need to look at if your suspect your salt chlorinator is not producing chlorine:

Salt levels
If you’re having salt water chlorinator problems, the first thing to check is that your salt levels are adequate. Check the manufacturer’s handbook for information about the salt levels required for your particular make and model of chlorinator and your pool size.

It’s important to understand that running your chlorinator without having enough salt in the water will cause damage to your electrodes so it’s the first thing we recommend to keep a close eye on.

You can test the salt levels yourself using testing kits available from your pool shop or DIY store or take a sample to your pool shop for testing. They will also advise you of the amount of salt that you should add to your pool, if required.

They will also generally give you an indication of the other elements of your pool chemistry which can affect the efficiency of your salt water chlorinator including pH, stabiliser, calcium and alkalinity.

Calcium Levels
If your pool chemistry test indicates a high calcium level, it’s worth checking whether there’s any obvious signs of this in your chlorinator cell. When you look at your cell, can you see any scaling on the electrodes?

If you can see deposits on the electrodes, this is generally a calcium build up and it will affect the performance of your chlorinator.

If this is the case, you will need to clean the cell to ensure optimal performance of your chlorinator and prevent damage to your chlorinator cell.

Chlorine levels
In the height of summer the amount of free chlorine in your pool can fluctuate dramatically depending on the factors such as whether you’re using a pool cover to stop the effects of the sun, how frequently the pool is used and by how many people.

In fact, sunlight is so effective at reducing the chlorination level in your pool that on a really hot summer day, the chlorine level can drop by 90% in just a couple of hours!

Similarly, if we’ve had one of our typical Brisbane summer storms, heavy rain can also reduce the amount of chlorine in the pool by diluting it.

Check the free chlorine levels in your swimming pool frequently, at least once a week, during the summer and adjust your chlorinator accordingly if you need to increase the chlorine levels.
