Salt vs Chlorine vs Mineral vs Freshwater

Choosing the right water system for your fibreglass pool is one of the most important decisions you’ll make. Each system offers different benefits in terms of comfort, maintenance, cost and long-term performance.

Chlorine Pools — The Classic Choice #

Traditional chlorine pools remain a popular option thanks to their effectiveness and low upfront cost.

Pros #

✔ Strong, reliable sanitising power
✔ Lowest upfront setup cost
✔ Simple chemical availability

• Can irritate sensitive skin
• Requires more frequent maintenance

Saltwater Pools — Soft, Gentle & Low Maintenance #

Saltwater pools generate chlorine automatically through a salt chlorinator, keeping maintenance simple.

Pros #

✔ Lower ongoing maintenance
✔ Gentler on skin and eyes
✔ Fewer chemicals to handle

Cons #

Mineral Pools — Premium, Therapeutic Water #
