The key to maintaining a clean and healthy pool is proper circulation of the pool water. But why is pool circulation important and how do you improve it? Let the professional Vancouver swimming pool contractors at Trasolini Pools help you out…

Why is pool circulation crucial?

The main reason is that the more circulation you have, the cleaner your pool is likely to remain and the less time you will need to spend maintaining it. Circulation is what moves your pool’s water around and passes it through your pool’s filter, which traps debris. 

Another important function of pool circulation is the proper distribution of your pool chemicals. When your pool’s circulation is inadequate, any chemicals that you add may not be evenly distributed and your pool will not be entirely sanitized.

Here are a few things that can occur as a result of improper pool circulation:

  • Your pool’s water can become stagnant which can make swimmers sick
  • Debris can build up in your pool which can damage the surface of your pool and its equipment
  • Your pool’s water may become cloudy, sludgy, or even develop an algae bloom, which can also cause problems for your pool’s equipment
  • Utility costs may increase 
  • Your pool’s chemicals can quickly go out of balance which will mean balancing your pool more often and using more chemicals

The best way to avoid any of these problems is to run your pool’s filter at all times, day and night. Do not turn your pool pump off if you leave on vacation; instead, ask a friend to monitor your pool while you are away. The more your pump runs, the more circulation you will have. 

What can I do to improve my pool’s circulation?


1. Keep an eye on your pool’s pump

Proper pool circulation begins with your pool’s pump, so ensure that it is serviced regularly and is functioning properly.

2. Run your pool’s skimmer

Skimming helps break up with the surface of the water and creates movement. This movement helps to circulate your pool’s water to some degree. Try to do this daily if you can or at least a few times every week. 

3. Use a vacuum to clean up debris

Again this helps create movement just like the skimmer, but it also helps to prevent buildup from occurring on the side of your pool and debris from piling up on the bottom. You should aim to do this at least once per week.

4. Keep your filter clean

Filters blocked with debris will also block your water from circulating, so make sure that you are checking these at least every other day. 

5. Brush dead spots

Dead spots occur in the areas of your pool that have poor circulation. These can be found near your pool’s steps, beneath skimmers, behind ladders, and in cracks and crevices. Brush these spots on a weekly basis in order to break up any accumulated debris and disperse it into the water and through the filter.

Other things to keep an eye on and ensure that they are functioning properly:

  • skimmer basket
  • return jets
  • main drains
  • pool valves
  • pump basket
  • return lines
  • filter pressure
  • filter O-rings

You can have the best pool equipment on the market, but if your pool circulation is not functioning properly it will not stay clean so make sure you stay on top of it.
