A green pool typically results from unchecked algae growth, but other factors can also be to blame — such as rust, organic debris like leaves and pollen, or imbalanced water chemistry.

In our tropical climate, heavy rain can dilute your pool’s salt and chlorine levels, making it easier for algae and bacteria to thrive. If not addressed, this can lead to unpleasant odours, cloudy water, and even health risks such as ear, nose, or throat infections.
