In light of the unprecedented floods in Queensland and New South Wales, we reprise this helpful advice from David Lloyd of International Quadratics on how to clean up and treat swimming pools after storms and floods.
Cyclones, storms, and flooding have several effects on swimming pools, including the following:
• Dirt and debris washed into the pool
• Phosphates introduced into the water
• Dilution of the chlorine causing algae to form
• Dilution of the salt and mineral content of the water
Below are some quick tips for handling the situation.
Step 1. The first step is to clean the pool of dirt and debris. Remove any large debris such as branches etc, and empty both the skimmer and pump basket. In the case of the water being very dirty such as when soil has been flushed into the pool, a heavy-duty floc may be required. Follow the label instructions of the floc you are using and then vacuum the pool to waste. See below for important information relating to keeping the pH high for flocs to work properly.
Step 2. Test and re-balance the pool water including the addition of salt and minerals where
required.
Step 3. Shock dose the pool.
Step 4. Add the required dose of phosphate remover to remove unwanted phosphates.
Step 5. In case of cloudy water use a clarifier.
Step 6. Add a winteriser treatment or maintenance algaecide.
