Why Should You Circulate Your Pool Water Regularly

A swimming pool that’s clean looks pleasant. But what’s more important is that when the pool water is clean, it’s both healthy and safe for people to use. Circulating your fibreglass pool water is essential to ensuring that the pool water stays clean.

If you don’t circulate your pool water on a regular basis, then bacteria as well as impurities could make your pool water unsafe to swim in.

Why Water Circulation Plays A Crucial Role In Keeping Pool Water Clean

As a fibreglass pool owner, you want to use your pool without worrying about whether it’s safe to use it. Pool circulation is key to making this happen. Circulation filters work towards ensuring that your pool water stays clean.

Circulation filters can also disperse chemicals as well as sanitising agents in the pool. Should the water of a fibreglass pool not be properly circulated, then that water turns into stagnant water. This is the kind of water that promotes the growth of algae as well as bacteria.

When it comes to maintaining your fibreglass pool, there are three main things that you should consider. The first of these includes cleaning your pool. Then, you also need to add the right amount of pool chemicals to the pool water. Finally, poor circulation is important. When you don’t circulate your pool water, then cleaning the pool and adding pool chemicals becomes pointless.

What Does Pool Circulation Actually Involve?

Irrespective of what size your pool is, it should be equipped with a filter as well as a pump of good quality. All the water that is in your pool needs to be pumped, properly filtered, and then cleaned. This is necessary in order to meet the pool standards set in Australia.

You should have a pool circulation system in place that is capable of cleaning and filtering your pool water within a period of twenty-four hours. Your pool pump will enable your pool water to circulate. Water is drawn from the fibreglass pool to the pool skimmer. This water will then travel to the pool pump and the filter.

The pool filter is then responsible for removing impurities as well as any debris that may be present in the water. The water, when it’s clean, is returned to the pool using the return jet. There are pools that come with more than one jet as well as skimmers. Our friendly New Zealand pool builders can help advise which would be best for your backyard.

What Are The Factors Affecting Pool Water Circulation?

There are several factors that affect your pool water circulation. These include:

Jet Settings

The jet is responsible for ensuring that clean water is returned to the pool. To make the most of your pool water circulation, your pool jets need to be multidirectional. This is so that water can be propelled through the entire pool. This especially applies should your pool come with multiple return jets.

If this isn’t the case, and you have just one jet, then ensure that your jet is turned downwards. It should be facing the opposite end of your skimmer as well. When your jet is turned in a direction that is downwards, it ensures that water that’s on the bottom of the pool is properly circulated. This way, you can improve the circulation of your pool.

Dead Spots

That section of your pool that doesn’t receive a lot of movement is known as the dead spot. This is that section of the fibreglass pool that is not able to reach the pool filter in order to get cleaned. Usually, dirt as well as bacteria tends to settle in these dead spots. In this context, fibreglass pools fare better than vinyl liner and concrete pools.

This is because, in vinyl liner pools, the surface is porous, making them more susceptible to turning into dead spots. Concrete pools also have surfaces that are uneven, where dirt and algae can get trapped. These are also great spaces for algae to grow.

Fibreglass pools tend to fare better as they come with a surface that is non-porous. This ensures that water can reach the pool filter more efficiently. Even pools that are regularly maintained and have equipment that are working properly can still develop dead spots.

This is why the interior surface of the pool needs to be brushed on a regular basis. You should also ensure that your return jets are faced in a way where they are towards potential dead spots in the pool. That way, you ensure that the circulation of the pool in that particular area is improved.

The Turnover Rate Of Your Pool

The term ‘turnover rate’ is used when describing the amount of time it would take for all the water in your pool to circulate through your filtration system. Exactly how much time it takes isn’t vitally important. However, you should still ensure that you are running your pool pump for around eight to ten hours every day.

When it comes to your pool’s circulation system, it’s your pump that’s responsible for doing most of the work. There are also some key things that you need to stay on top of to ensure that your pool water circulates properly. These include:

· You’ll need to regularly brush areas of the pool that are hard to reach.

· Your filter pump should be run for at least eight to ten hours every day.

· At least one of the jets needs to be directed towards the bottom of the pool.

· You’ll need to remove dirt, debris and insects from your skimmer basket on a regular basis.

The Pool Filter

It’s important that you ensure that your pool filter is cleared of debris. It should also have adequate pressure so it can work at its fullest potential. You can get in touch with your pool installer to learn more about pool filter maintenance.


Circulating your pool water on a regular basis is necessary if you want to maintain water health and ensure that your fibreglass pool is safe to swim in.

If you don’t circulate your pool water on a regular basis, then you could end up with pool water that’s contaminated with bacteria or algae. Use this guide to learn why pool water circulation is important, and how you can do it.
