Pool Turns Green and Cloudy After Rain

While the rain itself doesn’t generally harm your pool, it can dilute the carefully balanced chemistry in the water. This can alter your pH levels and dilute the chlorine or other sanitizes, allowing algae or other contaminants to gain a foothold. Once the algae spores have the proper conditions to grow, they multiply very quickly, which is why your clear pool can turn green overnight. A pool full of algae isn’t just unsightly – it presents potential health problems for bathers in the form of skin irritation, ear and eye infections, and gastrointestinal illness. It’s also possible for run-off from the storm to bring unwanted chemicals like nitrates and phosphates into the pool, further clouding the water.
