Beginner’s Guide to Freshwater Pool Systems

If you’ve ever dreamed of swimming in water as gentle as a fresh lake – no chlorine smell, no stinging eyes, and a silky-smooth feel – freshwater pool systems might be perfect for you. Traditional chlorine pools can be effective but come with downsides like odour, irritation, and chemical costs.

Freshwater systems such as Naked Pools and Enviroswim offer a low-chemical, eco-friendly alternative that’s becoming increasingly popular in Australia.

Here’s everything beginners need to know.

What Is a Freshwater Pool System?

A freshwater pool system sanitises water without relying on high levels of chlorine or salt. It uses minerals and electronic processes to kill bacteria and algae. The result is clean, low-chemical water that feels natural and gentle.

Chlorine levels in freshwater pools are often lower than tap water.

Both Naked Pools and Enviroswim are Australian-developed systems that use copper-silver ionisation plus oxidation to sanitise water.

How Do These Systems Work?

Mineral Ionisation

A control unit releases microscopic copper and silver ions into the circulation system.

• Copper prevents algae

• Silver kills bacteria

These ions stay active even in sunlight and do not require stabilisers.

Oxidation / Ultrasonics

Both systems break down organic waste (body oils, sweat, leaves).

• Naked Pools uses titanium plates to produce tiny, safe amounts of oxidisers

• Enviroswim uses electronic oxidation plus ultrasonic waves to disrupt organisms and biofilm

This keeps water clear without dumping chemicals.

Low Residual Chlorine

While almost chlorine-free, these systems may naturally generate tiny traces of chlorine — far below typical pool levels. Swimmers can barely detect it.

pH Management

Owners still need to maintain balanced pH (ideally 7.2–7.6).
Some systems offer automatic pH dosing for convenience.

Benefits of Freshwater Systems

1. No More Red Eyes or Skin Irritation

Swimmers enjoy soft, gentle water with no chlorine smell. Ideal for kids, those with asthma, eczema, psoriasis, or sensitive skin.

2. Lower Ongoing Costs

After installation, you dramatically reduce chemical purchases.
Pumps often run fewer hours, saving energy.
Equipment lasts longer due to reduced corrosion.

3. Environmentally Friendly

Freshwater pool water can often be used for gardening since it doesn’t contain harmful chlorine or high salt levels.
Reduced pump hours = lower carbon footprint.

4. Exceptional Water Clarity

Low dissolved solids mean water looks bright, clear, and “invisible.” Many describe it as swimming in natural spring water.

Things to Consider Before Switching

Upfront Cost

Installation requires an initial investment, generally offset by reduced long-term maintenance costs.

Learning Curve

You’ll need to monitor pH and ion levels, and occasionally replace electrodes.

Not Fully Automatic

You may still shock the pool in extreme situations (storms or heavy use), and routine checks are required.

Choose Trusted Brands

Stick with established systems like Naked Pools and Enviroswim to avoid unreliable off-brand ionisers.

Conclusion: Is Freshwater Right for You?

If you’re looking for a chemical-light, environmentally friendly, and skin-friendly swimming experience, freshwater systems are a fantastic upgrade. They offer clarity, comfort, lower running costs, and a more natural feel.

FAM Pool & Spa Solutions can help you choose, install, and maintain either system, ensuring you get the best out of your Sydney pool.
