Has your pool turned brown after a dust storm? Fear not, follow these steps to turn your pool water from brown to crystal clear.


1What is a brown pool?

A brown pool occurs when the water in your pool turns a murky brown following a dust storm. Unfortunately, a brown pool is unable to be fixed via traditional methods such as chlorine, algaecides and filtration.

Even after the majority of the dust has been removed, the airborne particulate matter will still be causing problems for pool owners and additional clarifiers will be needed to further assist filtration systems.

To get your pool back to its normal sparkling self, follow these steps.

2Remove debris

Remove as much of the debris from the pool as possible. And don't forget to check the skimmer basket and remove any debris that may be hiding in there.

3Check your equipment

Check all of your equipment. Power outages can cause chlorinators and timers to reset; while lightning can damage pumps and chlorinators.

4Backwash, rinse and clean

Backwash and rinse the filter, then clean the cartridge thoroughly.

5Shock and filter

Shock the pool with Super Shock and then run the filtration system.

6Test the water

Test the pool water by using the HY-CLOR mobile App or at your local Bunnings store and add balancing chemicals as required.
