A Beginner’s Guide to Pool Water Chemistry: Keeping Your Pool Clean and Safe

Owning a pool can be a rewarding experience, but maintaining it properly requires a solid understanding of pool water chemistry. Just because your pool water looks clean doesn’t necessarily mean it’s safe. Invisible contaminants can lurk in the water, potentially turning your pool into a hazard if your chemical levels aren’t balanced.

In this guide, we’ll break down the essential steps for maintaining your pool’s water chemistry so you can enjoy a clean and safe swimming experience.

Why Water Chemistry Matters

Even if your pool water appears clean, it may contain invisible contaminants. Sanitizers like chlorine play a crucial role in keeping these at bay. However, for sanitisers to work effectively, other factors like pH, alkalinity, and calcium hardness must be balanced.

Key Elements of Pool Water Chemistry

• pH Levels: Aim for a range of 7.2–7.6, with 7.4 being ideal. Use Focus pH Up or Focus pH Down to adjust levels.

• Alkalinity: Maintain between 80 and 120 ppm. This acts as a buffer for pH stability.

• Calcium Hardness: Ensure levels are 150–400 ppm to protect surfaces and maintain water quality.

Choosing the Right Sanitiser

• Chlorine: The go-to sanitiser, available in liquid, granular, and tablet forms.

• Saltwater Systems: Add salt to your pool, and the chlorinator continuously produces chlorine.

• Mineral Pools: These pools include added minerals like magnesium for extra benefits.

Water Testing: DIY or Professional?

You can use home testing kits, but professional testing provides the most accurate results. Bring your pool water sample to your local Poolwerx store for free testing and tailored chemical recommendations.
