Rain and thunder storms introduce many new things into your pool. Dirt, debris, rain water, and even lightning all affect the overall water chemistry of your pool, and can put a strain on your equipment. A quick cleanup is essential to minimize any potential issues like algae, cloudy water, or excessive filter pressure. The following steps will help you clean your pool after a rain storm.

Skimming The Pool

  1. Skim and brush your pool. This helps your system remove bigger debris and stirring up dirt to make it easier for the system to filter out.
  2. Clean your skimmer basket and all filter baskets in the system. This allows a steady flow of water to move throughout the system.

Shocking & Filtering

  1. In the evening, shock your pool with a product such as Power Powder Plus, or Chlor Brite. Shocking helps sanitize any contaminants or materials that were introduced to the water.
  2. Run your system for at least 12 hours to ensure proper filtration and circulation. This helps remove dirt and debris, along with circulating the chlorine in your pool.
  3. The day after adding the shock, check the PSI on your filter pressure gauge. If the pressure is sitting 8-10 PSI higher than normal, you need to clean out your filter.

Water Testing

  1. After potentially cleaning out or backwashing your filter, test your water either at home or by taking a sample to a local Leslie’s. Rain water and other debris affect your chemistry, most notably your pH and total alkalinity. Adjustments may be needed. At this time, you may also add a preventative algaecide like Leslie’s Algae Control if you wish. If you need to add pool chemicals, follow the directions of your Leslie’s pool professional.
  2. It is also recommended to test for phosphates. This can be done at a local Leslie’s store as well or with a test kit. Lightning increases the nitrogen in the air, which cause grass and algae to turn greener. These photosynthetic organisms then create a problem for chlorine. A chemical such as Leslie's Perfect Weekly will remove phosphates in the water and starve algae of food, therefore inhibiting their growth.
  3. 24 hours after adding any needed chemicals and/or cleaning your filter, if your water is still cloudy you can add a water clarifier like Leslie’s Ultra Bright to help the cleaning process.
  4. If any questions or problems arise, please contact a local Leslie’s professional to help you clean your pool after a rain storm.
