How to Balance Spa Water in Australia — Bioguard® Chemicals Guide

Keeping your spa water healthy, crystal clear, and perfectly balanced is essential for your comfort and safety. Poorly balanced water can damage equipment, irritate skin, and reduce the effectiveness of your sanitiser. In this guide, we’ll show you how to maintain perfect spa water using trusted Bioguard® chemicals — available online with fast Australia-wide delivery.

Why Water Balance Is So Important for Swim Spas

Unlike pools, spas have higher water temperatures and smaller volumes, which means the water chemistry changes faster. Balanced water helps:
• Prevent skin and eye irritation
• Protect pumps, heaters, and spa surfaces from corrosion
• Improve sanitiser efficiency
• Keep water sparkling clear and safe

5 Easy Steps to Balance Your Spa Water

1. Test Your Water Regularly

Use a reliable water testing kit to measure pH, alkalinity, calcium hardness, and sanitiser levels. Testing 2–3 times a week is ideal.

2. Sanitise the Water

Sanitiser keeps bacteria and algae at bay. We recommend Bioguard Armour 800g, a dual-action sanitiser and oxidiser designed for heated environments.

3. Shock the Spa Weekly

Shocking removes organic contaminants like sunscreen, sweat, and oils. Use Bioguard Purity for a shock treatment.

4. Balance pH and Alkalinity

• Raise pH using Bioguard Comfort Up
• Lower pH with Bioguard Aquality
• Stabilise pH fluctuations by increasing alkalinity using Bioguard Performance Up

5. Control Calcium and Foam

• Increase calcium hardness with Bioguard Shield to protect surfaces.
• Eliminate foam instantly using Bioguard Foam Go
