Pool Care After a Haboob


In 2011, every pool owner in Phoenix, AZ had to deal with incredible dust-storms called “haboobs”. These storms were widely considered some of the biggest Phoenix had ever seen.

So what is the best way to take care of your pool after a haboob? There are a few steps that, if followed, will help making caring for your pool after a dust storm easier.

  1. Ensure your filter is working properly. The debris entering your pool needs to come out somehow. By making sure your filter is working effectively, whatever enters your pool can be removed.  Once your pool is clean though, make sure to check the filter pressure. If your filter pressure is about 8-10psi higher than what it was originally, it would be a good idea to clean the filter. 
  2. Brush, skim, and check your filter baskets. Your system can’t handle all types and sizes debris. By skimming to remove bigger leaves and other outside materials, you can prevent any issues with the system caused by a blockage or clog. By brushing, you can speed up the cleaning process by moving dirt and other finer materials toward the main drain in your pool. Using a manual vacuum is also a good option to help remove dirt. This also prevents anything from getting stuck on your pool surface that could cause a stain, for example. Any debris that then makes it through the system will be caught in your filter basket, which needs to be cleaned regularly for optimal system performance.

  4. Shock your pool using a product like Power Powder Weekly Shock or Chlor Brite Granular Shock from Leslie’s. Algae spores and other material can enter your pool because of a storm. By adding the recommended amount of shock, you can make sure your pool stays sanitized. If you have a chlorine generator (salt system), you can typically find a “boost” feature to increase the amount of chlorine produced by the cell for a short period of time.

  6. Run your system overnight. Brushing and shocking won’t be effective at cleaning your pool if the water isn’t being filtered and circulated. Running your system for an extended period of time allows not only the debris you’ve stirred up in the water, but also the material that has been killed by the shock, to be removed by your filter.
  7. Manually test your water or bring a sample to a local Leslie’s store. Rain and other debris can interfere with your pool’s water balance and sometimes things need to be adjusted afterward. In order to get a sense of what has chemically changed from the storm, a simple water test can show you what you need to do to make sure your pool is ready for use.
