How to Avoid a Green Pool

Keep your water crystal clear all year long

There’s nothing worse than stepping outside to your backyard oasis only to find the water looking cloudy—or worse, green. A green pool can appear almost overnight, especially when water chemistry or circulation gets off track. Algae thrive in still, unbalanced water, but with a few consistent habits, you can keep your pool sparkling clear and inviting no matter the season.

Watch Your Water Balance

Even when swimming season slows down, your pool’s chemistry still needs attention. Low sanitizer levels are the most common cause of algae, so testing your chlorine, pH, and alkalinity weekly helps keep things under control. When your pool’s balance is right, algae simply can’t take hold.

Keep That Water Moving

Stagnant water is algae’s favorite environment. Make sure your pump runs every day to keep your water circulating and your filter doing its job. Good flow means your sanitizer reaches every corner of the pool—leaving no dark spots for algae to grow.

Brush, Vacuum, and Stay Consistent

Algae like to cling to shady corners, steps, and pool walls. Brushing your pool once a week keeps buildup from starting, while regular vacuuming removes debris that feeds algae. Think of it as light housekeeping for your pool—small efforts that make a big difference.

When in Doubt, Shock It

If your water starts looking dull or cloudy, it’s time for a shock treatment. This quick boost of chlorine kills bacteria and clears up any early algae growth before it turns your pool green. It’s an easy reset that keeps your water healthy and clear.
