Cleaning Your Pool After Flooding or Storms

Cleaning your pool after a flood can be a daunting task. Mother Nature is often unpredictable and sometimes there are some really unpleasant surprises. Floods, heavy storms and dust storms, before you know it, they wreak havoc.

A storm can spell disaster for your beautiful, crystal-clear swimming pool. Storms can wash mud and other gunk into the water, dilute and disturb your chemical balance, and, in extreme cases, even destroy your pool equipment.

Storms can also create unforeseen hazardous conditions and your safety comes first, so before trying to restore your pool, please make sure that you and the area surrounding your pool are safe. As such here is a general guide to help restore your pool after a storm.

Inspecting Your Swimming Pool After Flood And Storm

The 1st and most important step is to properly assess what has actually happened to your pool in the storm. It is recommended to start by checking if any of your pool equipment (pump, filter, etc.) has been damaged or destroyed during the storm, as any further cleaning will rely on all of those being in working condition.

Next, check the condition of the actual water. If by some miracle your pool looks clear, simply scoop or vacuum any leaves and other debris out of the water and take a water sample to your local pool professional ASAP. Then balance the water as directed and resume having a lovely blue pool. However, in the likely event, your pool is cloudy/muddy or green, special treatment will be required.

Cleaning Cloudy Or Muddy Pools After The Storm

Storms have the unfortunate habit of washing a whole host of gunk into the pool, including dirty water, mud and a whole host of other debris.

Either way, this is all stuff that you don’t want going through your pool filter if you can help it. The best way you can fix your pool from this state is to floc all of the gunk in the pool to the bottom and vacuum it out to waste, and these steps will outline the process.

Cleaning your Pool After the Flood, Heavy Storms or Dust Storms

For flocking a storm-contaminated pool, it is recommended to use a strong granular floc. These instructions work for most granular floc products, but please consult the instructions of your specific product for the best results.

  • Try to scoop out any large physical debris before starting this process, like large sticks, rocks etc.
  • Adjust your pool’s pH so it is approx. 8.2. Whilst under normal circumstances, you should keep your pool’s pH level between 7.2-7.6, most granular flocs are most effective in a high pH environment. This can be achieved by adding an appropriate dose of soda ash (pH increaser) to your pool. Please check the dosage rates of your specific product.
  • Mix the granular floc up in a large bucket of water. You should need approx. 2kg of floc for every 50kL of water.
  • Pour the floc solution around the pool. Make sure that you don’t pour it out all in one place but rather walk it around the pool as this will help it spread and mix in with the pool quicker.
  • Set your sand filter to recirculate or remove your filter cartridge. Then turn your pump on for a few hours to help disperse the floc evenly amongst the pool.
  • After that’s happened, turn your pump off and leave your pool alone for approx. 24 hours, to allow the floc to sink everything to the floor.
  • Proceed to SLOWLY & CAREFULLY vacuum your pool, ideally out to waste. The faster/less careful you are, the more likely you are to disturb the gunk on the bottom of the pool and the more likely it is you’ll have to let it all settle again and come back for a 2nd pass. If you own a cartridge filter and don’t have a waste line installed, you will have to vacuum the gunk into your filter cartridge and will probably need to clean the cartridge multiple times during this process. You’ll also probably need to get a new cartridge after you’re finished.
  • Once the pool is back to being blue & crystal clear, take a water sample to a local pool professional ASAP and balance the water as directed.

The Pool is Green

This unfortunately means that the storm has prompted algae to bloom in your pool happily. If your pool is muddy/super cloudy and has algae, you should follow the steps outlined above before attempting to treat the green algae. Thankfully, Green & Mustard algae are relatively easy to treat if done quickly.
