How to Optimize the Quality of Your Pool Water

Summer. Long hot days and summer nights spent lounging by the pool, refreshing morning swims, and friends dropping by for an afternoon dip.

The pool is the place to be – and it’s getting a lot of use. So how do you keep your pool clean and fresh all summer?


How to Keep Your Pool Clean

There are a few tips and tricks to keep your pool clean and clear right into the fall:

  1. Water Level
  2. Chlorine
  3. Filtration and Circulation

If you follow these steps it will ensure your pool will not harbour bacteria or grow algae and turn into an expensive duck pond.

Pool Water Quality Tip No. 1

Water evaporates – everyone knows that don’t they? Not many people think about the water in their pool evaporating, but it does. In the high heat of the summer, the water in your pool can evaporate quickly, and if the water level drops below the skimmer, the pump may overheat and burn out.

Water and sun make the perfect growth environment for algae. And the only way to keep algae at bay is to use chlorine in your pool. You must check the chlorine levels to make sure they don’t drop too much, because just like water, chlorine also evaporates when it is hot. Preventative disinfecting can stop the proliferation of bacteria and algae throughout summer and into fall. But since most microorganisms cannot grow in water below 10°C, you can cut back on the chemical use during cold weather and winter months.

Pool Water Quality Tip No. 3

Last, but by no means least, is the filtration and circulation system in your pool. It is widely recommended to leave the pool filter running at all times, especially during heat waves and when the water temperature exceeds 27 °C. Filtering helps reduce the growth of algae. Bacteria and microorganisms grow faster in warmer water and can cause an imbalance in water quality.


It is best to filter during the day when the algae grow through photosynthesis. Filtration helps disperse sanitizers throughout the pool, which also helps prevent microorganism growth.

While filtration is most important during the day, it is also a good practice to filter your pool at night because some sanitizers are compromised by the UV rays.

In addition to filtration, and to maximize the efficacy of sanitizers, proper circulation will help keep your pool algae and bacteria free. When water does not circulate it becomes stagnant, and this creates an environment that allows the growth of microorganisms. Poor circulation is responsible for roughly 90% of all pool water problems

The key point to remember is that algae grows in heat and sunlight, so filtering and circulating your pool water as much as possible during the summer months will help keep it clean.  If leaving the filter running 24/7 is not an option for you, remember to turn the filter on during the day.
