If you're new to owning a pool or spa, water care can seem overwhelming. With so many chemicals, testing routines, and maintenance products available, it's easy to wonder where to start. The good news is that preventing green water is much simpler than many first-time owners think.
Green water is usually caused by algae, which thrive when sanitiser levels drop or water chemistry becomes unbalanced. By following a few simple maintenance habits and using the right chemical products, you can keep your pool or spa crystal clear all year round.
Why Does Pool Water Turn Green?
Algae spores are naturally present in the environment and can enter your pool through wind, rain, leaves, or even swimmers. Under the right conditions, they multiply quickly, turning water cloudy or green and making pool surfaces slippery.
Some of the most common causes include:
- Low chlorine or sanitiser levels
- Poor water circulation
- Dirty or blocked filters
- Unbalanced pH and alkalinity
- Hot weather and heavy pool use
The best solution is to stop algae before it has a chance to grow.
Start With the Basics
For beginners, the easiest maintenance routine includes just a few simple steps.
Test your water at least once a week to monitor chlorine, pH, and alkalinity. Keep your pump and filter running as recommended to circulate water properly, and clean your filter regularly to maintain good performance.
It's also important to shock your pool or spa when needed, especially after heavy use, storms, or periods of hot weather. Shocking removes contaminants that normal sanitiser levels may struggle to eliminate.
Finally, using a preventative algaecide can provide an extra layer of protection by stopping algae before it becomes visible.
Chemical Kits Make Maintenance Easier
Instead of buying individual products, complete chemical kits provide everything you need in one convenient package. They're especially helpful for new pool and spa owners because they remove the guesswork from water care.
Here are some excellent options available from Spa & Pool Supplies.

Don't Forget Shock Treatments and Algaecides
Chemical kits provide an excellent foundation for water care, but every pool owner should also keep a reliable shock treatment and algaecide on hand. These products work together to prevent green water and quickly restore water quality when conditions change.
BioGuard® MSA Extreme Algaecide is a powerful copper-based algaecide that targets and eliminates even stubborn algae while helping prevent future outbreaks. It's an excellent preventative treatment, especially during warmer weather or after periods of heavy pool use when algae is more likely to develop.

Its fast-dissolving multifunctional granules restore water clarity quickly, leaving your pool clean, sparkling, and ready to enjoy.
Using these products alongside regular water testing, proper filtration, and a quality chemical kit makes it much easier to prevent green water rather than dealing with a full algae bloom later. Together, they provide a simple, effective maintenance routine that helps keep your pool healthy, balanced, and swim-ready all year round.
