Choosing your pool interior colour

Once you’ve made the decision to build a pool (or renovate your existing pool) with an Aqualux pool finish, the next difficult decision to make is ‘Which colour or pattern do I pick?’.

When we started making pool liners back in the 1970’s, it wasn’t a difficult choice – light blue or dark blue! Now, there is always at least 14 Aqualux colours to choose from- often 16 or even more. Most people will start their decision-making process online – looking at photos of pools. And while that can be a terrific help, it can also be a little overwhelming, as the same colour can look completely different in another pool (and even in the same pool!).

Aqualux in ‘Antique’ looks completely different in each of these pools. Water chemistry, landscaping and lighting are all factors.

How can the same colour look so different?

Once your pool has been filled, you’re not really looking at the liner colour anymore – you’re seeing the water in front of the liner – and this is where physics plays a part.

Clean water has no colour – so when you put it in a glass, it looks clear. But in a large body of water, such as the ocean, a swimming pool or even a spa filled with the same water, it will appear blue or green. This is because light is made up of all the colours in the spectrum, and when it hits an object, the object absorbs some colours, and reflects others. When light hits the water, the water will absorb the red, and reflect back blue. So even in a pure white pool, the water will always appear blue.

There are many other factors that will affect the watercolour too. Size and depth of the pool, landscaping and surrounds, water balance and of course lighting all play a huge part in determining the look of the watercolour – and this is why it can be so hard to select the right liner colour for your pool.

If you’re struggling to decide on a colour, the first step is to decide if you want a light coloured pool or dark.

Benefits of a darker pool interior include a warmer pool, which will look cleaner – even if it’s not. The darker the interior, the harder it is to spot dirt, leaves and other stains in the pool. In contrast, the lighter the pool interior, the more obvious any dirt or leaves are – so if you live in an area with lots of dust or leaves, and you don’t think you’ll be able to keep on top of the cleaning, then you may like to stick with a mid to dark coloured pool – or invest in a leaf and debris cover.

Blue water or Green?

If you are looking for a green, aqua or turquoise pool, you don’t have to pick an obviously green pool liner like Maldive – anything with tan or yellow (such as Aqualux Sandstone and Coral Sand) or black colouring (like Antique and Kiama) also usually throw green.

Viewing distance

If you’re converting over from a plain painted or fibreglass finish, you may initially find some of the patterns of Aqualux a little ‘bold’- however, don’t get too caught up in the print you see on the sample. The patterns are designed this way to give your pool the most vibrant appearance possible, and the more contrast in the pattern, the more depth of colour your pool will give.

The patterned surface also helps to hide any flaws in the pool shell – so the more contrast in the pattern, the better job it will do of disguising imperfections – definitely something to consider if you are resurfacing a pool with Osmosis.

Remember, you’ll generally be looking at your pool interior from at least a couple of metres away, and most of it is underwater (or all of it, if you’re having a waterline tile) – so while a pattern may seem a bit busy when you look at it up close, it will look far more subdued once installed.

Contrast or Blend?

This is another decision that is generally fairly easy. Do you want your pool to blend with your garden, and look like a natural addition, or do you want it to ‘pop’? For a natural, muted appearance, select a colour that tones in with your pavers and surrounds – such as charcoal pavers and an Antique or Kiama interior. But if you want to make those interiors pop, then use a white or sandstone paver. If you really want your interior to pop, you cant go past the vibrance of Bahama or Maui – and there’s a reason why these have been two of our most popular colours for the last few years.

In the end though – the only thing that matters is that you pick a colour that you’re going to like looking at – because chances are, you’re going to be looking at it for about 15 years! To look at some different pools, go to our Liner Gallery – just select the colour you’re thinking of, and it will filter out the others.

Testing your pool water (chemical balance is important)

As a pool owner, it’s important to keep your water ‘balanced’. The best time of day to test your water is first thing in the morning, and after the filter has been running for an hour or so.

The correct chemical balance varies depending on your pool interior finish. For domestic purposes, for a vinyl-lined pool or Aqualux Pool finish, we recommend the following levels:

pH: 7.4-7.8

Total Alkalinity: 100 – 150ppm

Calcium Hardness: 200 – 400ppm

Free Chlorine 1 – 3ppm (Non-Heated Pool) or 2 – 4ppm (Heated Pools)

Stabiliser 30 – 50ppm

Saturation Index -0.1 – + 0.4

When collecting a water sample from your pool, take it from around the middle of your pool (rather than from one end), and as far as possible from any return jets or the skimmer. Using a clean container or bottle, hold it upside down so that the opening is facing the pool floor, and insert it into the water, about elbow deep. Turn it over and allow it to fill before bringing it back out of the pool.

If you’re taking it to your pool shop for testing, go straight there – don’t stop off at the shops on the way there, as your sample can degrade after a period of time – even 15 minutes in a hot car can skew your results.

If you’re using test strips, take care to follow the instructions from the manufacturer. A basic rule of thumb is to quickly dip the strip in and out of the sample container (not straight into the pool) and hold it still (don’t shake it or flick the water off) – just hold it still for 15-20 seconds. Immediately check the colours against the strip on the back of the test strips container – your most accurate results will be at 15-20 seconds, as the colours can continue to develop as time goes on. The most important readings you’re looking at are Free Chlorine and pH.

At home test strips are a convenient way to keep tabs on your water quality – most people will do these weekly, with a proper test with their pool shop once a month.

NOTE: If you have just put a pool cover on your pool, be aware that your chemical consumption will be reduced by about half. If you have an automatic dosing system, you should turn it down to around 50%, and monitor your chlorine levels daily, adjusting settings to suit until they have stabilised.
