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

Keeping your swim 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 swim spa water using trusted Bioguard® chemicals — available online with fast Australia-wide delivery.

Why Water Balance Is So Important for Swim Spas

Unlike pools, swim 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 Swim 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 2kg, 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 Lite for a shock treatment.

4. Balance pH and Alkalinity

• Raise pH using Bioguard Balance Pak 200
• Lower pH with Bioguard Lo'N'Slo
• Stabilise pH fluctuations by increasing alkalinity using Bioguard Balance Pak 100

5. Control Calcium and Foam

• Increase calcium hardness with Bioguard Balance Pak 300 to protect surfaces.
• Eliminate foam instantly using Bioguard Foam Go
