What is clear when it comes to a pool? Your “clear” might look cloudy to me, or vice versa. Ideally, you should be able to see a coin on the bottom in the deepest part of the pool.

Here are some tips to help keep your pool crystal clear:


During the summer a pool filter must run for at least 10 – 12 hours during daylight. During winter months, the running time can be cut back to 4 daylight hours a day. If your pool is not circulating for these minimum periods the water is likely to become cloudy. Correct running times can easily be automated by using a plug-in timer. If you’re not already using a timer, then please ask us to install one on our next visit.


The big round thing in your filter shed is a sand filter. This is full of sand that catches all the dead algae, dirt and grease etc and is the main thing that keeps your pool clear. After a week of filtering, the sand in the filter becomes very dirty, and its ability to catch particles is seriously hindered. Backwashing your filter will clean the sand and enable maximum filtration to happen again.

A good way to tell if your filter needs backwashing is by looking at the pressure gauge. It will rise as the sand becomes clogged with dirt etc. It is important to note that filter sand has an average life expectancy of 4 – 5 years. Please contact us if you suspect your filter sand might have reached the end of its useful life. We can also replace faulty pressure gauges if necessary.


It is important that there is water movement through the entire pool. A struggling pump, a full skimmer basket, or a clogged or damaged hair and lint pot can decrease water circulation. A cracked skimmer basket or hair and lint pot can also have serious implications for your pool and equipment.

Please contact us for replacement baskets, or for further solutions to improve circulation in your pool. We can also arrange for your pump to be checked and serviced if necessary.


Certain pool surfaces will eventually deteriorate, causing them to begin ‘chalking’ or letting off a fine white dust. This is especially prevalent on old painted and marble plaster surfaces.

You may find the problem ‘flares up’ after you vacuum your pool, or with high pool use. The simple answer is it’s time to repaint or resurface your pool. Please contact us for advice or to arrange a quote for repainting or resurfacing.
