What if my pool has already gone green?
If your pool has already gone green, you don't have to empty it.
You can kill the algae with a shock dose of chlorine and some advice from your pool shop on filtration. You won't be able to use the pool until the chlorine levels are reduced again.
How can pool chemicals save water?
By maintaining the correct balance of chemicals in your pool year round, you will prevent your pool water from going green over winter. This means you won't need to empty and refill the pool in spring. Monitoring the chemicals in your pool will also prevent you from having to discard polluted water.
Water restrictions will affect how you fill a new pool or top up an existing one. You may have to use a bucket or order water in via a carting service depending on local water restrictions. Check with your local water provider.
