How to look after a swimming pool in hot weather

If you are lucky enough to live in a warm climate and have the luxury of owning a swimming pool you may be at an advantage over swimming pool owners who live in a colder country or somewhere where you have an ambient average climate, where owning a swimming pool is seen as more of a luxury. With very fewer swimming pool supply companies and fewer swimming pool service companies makes owning a swimming pool often more expensive. If you need to know how to look after a swimming pool in hot weather you will find it very straight forward, however, you will spend more time looking after a swimming pool if you lived in a country with a cooler climate.

Places such as Australia, Indonesia, Malaysia, Thailand all will have ample swimming pool supplies, and you will also the Quest chemical free swimming pool sanitizer available in many of these countries.

Due to global warming the temperature will increase in 2021, and so far year on year it has been warmer and warmer so this means more and more people will be investing in swimming pools to keep them cool and will need products to look after the swimming pool in the hot weather.

We will also expect in 2021 according to sky news weatherman Tom Saunders more cyclones, and also may be more than one wet La Nina for the first time since 2012. So this will affect looking after your pool in a different way than what you would expect in hot weather. If you have extremely hot weather it will cause many problems with your swimming pool water condition.

However, if you contacted Quest of one of its distributors or agents they can explain how using our system to nurse your pool water with the treatment of electrolysis.

You must be vigilant of extreme weather conditions from very hot and wet.

Extreme Heat

This will result in a number of issues the first and most obvious is evaporation. Swimmers jump in the pool to cool down and would probably invite friends and family over so this all adds to the water evaporating. The pool owner then normally pours in more chlorine which results in the ph level being not neutral and then has adverse effects on the swimmers breathing, skin condition, general health and wellbeing.

You can also add calcium hardness reducer which will save you adding more water into the pool. But once you start adding chemicals into your pool this will mean you will need to run your Quest system at maximum ionisation and oxidisation for at least for twenty-four hours to sanitise your swimming pool water.


The global weather patterns are changing all over the world. You may live in Alice Springs and have had no rainfall for months, but then a downpour such as last week twentieth of December 2020. You can’t just watch the pool fill up with rainwater, looking after your pool in a hot climate needs to be done when it’s raining also.

It’s perfect for Algae

The Heat and humidity is a perfect spawning ground for our friend Algae. The only solution used to be chlorine that people used to throw into the pool in the evening when the temperature drops. (Sorry no offence if you still do this, but this is outdated and harmful technology) Now it’s simpler just to increase the current to the ECU unit of the Quest system to ionise the water with an influx of copper ions.

Be aware of phosphates in your pool. Algae thrive on phosphates and they provide a source of nutrition. Phosphates enter the pool as dust,dirt, rainwater, bird faeces, pet’s hair, leaf,twigs, garden foliage and other foreign bodies in pool. If you add chlorine into the pool it will not break down these elements. The only way to destroy these is by using an oxidiser which is another process that the Quest system uses.

How the oxidiser works is it that it attacks the phosphates in the pool by targeting the outer cells and takes an electron rendering it useless and then the atom dies. It is similar to if you leave an apple for a while and it starts to turn brown and go off, or metal left outside turns brown and rusts. Chemicals such as chlorine and potassium are often used as oxidisers if you don’t use an electronic oxidiser such as the Quest System.

Besides phosphates in the poolyou have to eradicate biofilm. Biofilm is a layer of cells that attach to a surface. As bacteria grow and divide spread to cover a large area then gather and form in mushroom shape compounds that gather more bacteria and become resistant to chemicals such as chlorine.

This biofilm bacteria then spreads into the pipe work and plumbing system. The bacteria you would think could be flushed away by high pressure water , however they secrete on sticky substance called polysaccharide and stick firmly to the surface.

The only element that can attack this bacteria is silver and combined with the copper and de scaler these three processes can attack the outer cells and kill this bacteria.

One of Quest’s directors Simon Sverdloff has found that the Australian bureau of meteorology has predicted that 2021 will be the hottest year on record due to many factors include climate warming due to man. This must stop and using electronics rather than chemicals in water sanitation will help tremendously.

Also, the climate in 2021 will result in a rare convergence of two prominent weather events, one being in the Pacific Ocean and the other in the Indian Ocean. This will more than likely result in an El Nino event that will result in extra dry and hot weather, so owning a pool means you need to be more vigilant.

Balancing the Ph level

I know I keep mentioning this but balancing the ph level is so extremely important. If the water balance is not correct for example the water balance is too high using chemicals such as chlorine will be less effective and the water becomes dull and cloudy. If you add acid to acid it will balance out, so add acid to the water. If the water ph level is too low the swimming pool water will sting your eyes and your skin starts to become itchier and can also affect your breathing. It can also start to eat away at the pool lining or tiles and cause scaling. You will need to add a buffer or an alkaline to balance the swimming pool water back up to a level of around 7.2-7.6.

This sounds messy and adding chemicals is not good for the environment or your health. So, the simple answer is to use a Quest pools system that uses electrolysis so there is no need to keep adding chemicals if the weather gets too hot.

Quest pools recommend these tops tips on how to look after your swimming pool in hot weather:

  1. As mentioned above check your chlorine levels if you are still using chlorine and swimming pool ph levels every two days. If you have had an increased number of bathers in the pool than normally or the weather has increased in temperature.
  2. Make sure your skimmer basket has been emptied and the hair and lint pot has been cleaned out, this is normally located near your filtration pump.
  3. To rebalance your swimming pool water you can either take a sample to your local pool store to get the water analyzed or use one of the latest analyzers such as the keto Ai system that uses a probe to monitor the pool’s ph levels and copper ion content.
  4. Use an algaecide to keep the algae from spreading or if using a Quest system simply increased the ionizer to maximum power until the algae have dissipated and returned the power to minimal again.
  5. Switch on the filtration system for at least six to eight hours a day to filter out any large phosphates, also use the oxidizer on the Quest system if you have one to help break down the foreign bodies in the swimming pool.

One last piece of advice, if you do live in a country where the cost of water is high for example the Middle East, South East Asia, Australia you will also be making sure you don’t wastewater. This may mean turning off the pump when the pool is not in use. However, this cannot be done when using sanitizers such as salt-water chlorinators, chlorine, Ultraviolet, etc. If you do use a Quest swimming pool system the electrolysis system will give you protection as the copper and silver ions are already in the pool water and do not need to be pumped through a filtration system. So not only are you using the same water but reducing the pump usage also by 50% in some cases or more.
