Spring is the season of renewal—and for pool and spa owners, it’s also the time when algae love to make an appearance. After months of cooler weather, algae spores thrive as temperatures rise, daylight stretches longer, and water circulation increases. Left unchecked, these tiny organisms can quickly transform clear water into a cloudy, slimy problem.
The good news? With the right knowledge and maintenance routine, you can prevent algae from taking over your pool or spa this spring.
Algae spores are present everywhere, carried in by wind, rain, and even swimmers. During colder months, their growth slows, but once warmer weather sets in, algae multiply rapidly. Pools and spas that haven’t been maintained consistently are especially at risk, as unbalanced water and debris create the perfect breeding ground.
Understanding the type of algae in your pool or spa helps you choose the right solution:
Green Algae – The most common, causing cloudy water and slippery walls.
Mustard (Yellow) Algae – Resistant to chlorine, typically found in shady corners.
Black Algae – Deeply rooted and the hardest to eliminate, often appearing as dark spots on plaster or grout.
Like most things, preventing algae is easier than removing it. Here’s how:
Test and Balance Water Regularly – Keep pH, chlorine, and alkalinity within range.
Maintain Circulation – Run pumps at least 8–12 hours a day to avoid stagnant water.
Brush and Vacuum Surfaces – Stop algae from clinging and spreading.
Shock Treatments – Give your pool a chlorine boost to kill hidden spores.
Algaecide Protection – A preventative algaecide provides a safeguard against blooms.
This powerful, non-foaming formula is designed to fight tough algae quickly while preventing stains. Safe for use with chlorine and bromine systems, it’s a reliable way to keep water clear and inviting.
Don’t worry, algae outbreaks are manageable.
Brush pool and spa walls thoroughly.
Shock with a strong chlorine dose.
Run your filter continuously until water clears, backwashing when needed.
Finish with a quality algaecide to stop it from coming back.
A crystal-clear pool or spa doesn’t just happen, it’s the result of regular care and smart maintenance. By keeping your water balanced, your system circulating, and your surfaces protected, you can enjoy clean, inviting water all season long.
