What is Chlorine Pool Stabiliser?

Chlorine is one of the pool chemicals that we spend the most money on over the course of our pool ownership. Its job is to sanitise our pool and to prevent algae and other bacteria from growing. One problem with chlorine is that it evaporates, just like the water in your pool. This is where stabiliser comes in. It protects your chlorine from the sun, giving it enough time to work its magic before it’s evaporated by the sun.

What Is Stabiliser?

Stabiliser is somethings referred to as pool conditioner, though if you’re after its most technical name simply refer to it as cyanuric acid. You can purchase stabiliser in either liquid or granule form.

As we mentioned above, stabiliser slows down the rate at which your chlorine evaporates. Though just as with any pool chemical, you don’t want to add too much to your pool, as it could begin to cause a whole new set of problems.

When you add too much stabiliser to your pool it will eventually render your chlorine ineffective. The only way to fix this is to remove some water from your pool and top it back up with clean water again. Then, you will need to rebalance all your chemicals.

How Much Stabiliser Should You Add to Your Pool?

Advice on how much stabiliser you should add to your pool range from a few parts per million (ppm) to 100 ppm. We recommend that you talk to a pool servicing professional like us, so that you can get advice based on your individual pool needs.

As a general rule of thumb though, if your stabiliser is at 50 ppm or higher you won’t receive significant UV protection and algae has an increased chance of growing. If you go below 50, you still want to regularly monitor your pool and perform chemical tests.

How often should you use stabiliser?

Unlike with chlorine, you don’t have to spend a tonne of money on stabiliser. You can use chlorine pool stabiliser just once per year – that’s it! Unlike chlorine and other chemicals in your pool, stabiliser doesn’t evaporate. It simply just remains in your pool.

Unless a significant amount of rain falls or lots of water splashes out of your pool then your stabiliser typically shouldn’t be affected. Also, if you use stabilised chlorine then you’re adding small amounts of stabiliser to your pool as you go throughout the year anyway.

Outlying cases where you will need to separately add stabiliser to your pool water include when its diluted due to external influences such as rain. Also, when concentration levels become too high and you then need to remove and top your pool water back up.

How to Add Stabiliser to Your Pool

When it comes to pool chemicals, some can be added directly to your pool water while others can be introduced to your pool via the pool filter. When it comes to stabiliser, we recommend neither of these techniques.

Stabiliser is highly concentrated and adding it directly to your pool or through equipment can lead to major damage. That’s why we recommend you get a 20-litre bucket, fill it with water and slowly dissolve the stabiliser in there. Then, pour the bucket out into your pool water. This way, you won’t risk damaging any pool chemicals. If you’re not sure, then contact us and we’ll be more than happy to help you out.

When to avoid Stabiliser?

If you own an outdoor pool then there’s no reason to avoid chlorine pool stabiliser. Just be sure you’re not adding in too much over time, so you don’t damage any of your equipment. If you own or manage an indoor pool though, then there’s really no point in using stabiliser, as your chlorine isn’t exposed to the sun’s UV rays.
