Naked Pool Systems - the TRUTH
The Complete Guide to Naked Freshwater Pool Systems in Australia
Considering a Naked Freshwater Pool System for your Australian home? This comprehensive guide explores everything you need to know about this increasingly popular pool sanitisation technology. We'll cut through the marketing hype and give you the facts about how these systems work, their true costs, and the maintenance commitment required.
How Does the Naked System Work?
The Naked Freshwater System is a copper and silver ionisation technology that reduces—but doesn't eliminate—the need for chlorine in your pool. Here's the simple explanation:
- A digital control unit sends a low-voltage current through copper and silver electrodes
- This releases microscopic copper and silver ions into your pool water
- Copper ions act as an algaecide (preventing algae growth)
- Silver ions work as a bactericide (killing bacteria)
- You still need to add a small amount of chlorine (0.2-0.5 ppm) as an oxidiser
- The system runs continuously while your pump is operating
Key Point: This is NOT a chlorine-free system. It's a low-chlorine system that uses mineral ions as the primary sanitiser, with chlorine as a necessary supporting element.
Advantages vs Disadvantages
✓ Advantages
- Reduced chlorine usage: 80-90% less chlorine needed
- Softer water feel: Less harsh on skin, eyes, and hair
- No chlorine smell: Minimal chloramine formation
- Swimwear protection: Less fading and deterioration
- Stable sanitiser: Ions remain active even when pump is off
- Clear water: Copper ions provide natural clarification
- Long-term algae protection: Residual copper prevents algae
✗ Disadvantages
- High initial cost: $2,500-$4,000 for system and installation
- Complex water chemistry: Requires precise balance
- Staining risk: Copper can stain if levels get too high
- Regular testing required: More parameters to monitor
- Not truly chlorine-free: Still need oxidiser
- Electrode replacement: $300-$500 every 12-24 months
- Professional servicing: Often needed for proper balance
- Slower acting: Takes time to build ion levels
⚠️ Critical Warning: Not a "Set and Forget" System
Despite marketing claims, Naked pools require MORE attention than traditional chlorine pools, not less. The delicate balance of copper, silver, pH, and oxidiser levels means these pools need constant monitoring. Many pool owners find themselves spending more time on maintenance than with a standard salt or chlorine system.
Reality Check: If you're looking for a low-maintenance pool solution, a properly automated salt chlorinator with pH control may be a better choice than a Naked system.
Maintenance Requirements
Daily Maintenance
- Check and adjust oxidiser (chlorine) levels - must maintain 0.2-0.5 ppm
- Monitor pH levels - critical for ion effectiveness (7.0-7.4 ideal)
- Visual inspection of water clarity
- Check ioniser display for proper operation
- Run pump minimum 8-10 hours in summer, 6-8 hours in winter
Weekly Maintenance
- Test copper levels (0.2-0.4 ppm ideal, never exceed 0.5 ppm)
- Test silver levels (difficult without professional kit)
- Complete water chemistry test (pH, alkalinity, calcium hardness)
- Adjust ioniser output if needed
- Shock treatment if required (use non-chlorine shock preferably)
- Clean skimmer baskets and check filter pressure
- Add oxidiser as needed
Monthly Maintenance
- Professional water test recommended (many parameters home kits can't test)
- Clean electrodes if calcium buildup visible
- Check and clean salt cell if you have hybrid system
- Balance calcium hardness (200-400 ppm)
- Test phosphate levels
- Inspect electrode wear
- Backwash filter thoroughly
Yearly Maintenance
- Replace electrodes ($300-$500 depending on pool size)
- Service ioniser control unit
- Deep clean or replace filter media
- Professional inspection of entire system
- Water dilution if TDS too high
- Check and service pump and other equipment

| Professional Testing (Monthly) | $30-$50 | $0-$30 | $0-$30 |
| Electricity (Pump runtime) | $60-$100/month | $50-$90/month | $55-$95/month |
| Annual Running Cost (Avg) | $1,500-$2,200 | $800-$1,400 | $900-$1,300 |
Water Testing Requirements
Copper Levels
Ideal: 0.2-0.4 ppm
Maximum: 0.5 ppm
Test: Weekly
Warning: High levels cause staining
pH Level
Ideal: 7.0-7.4
Critical: Must be lower than typical
Test: Daily
Note: Affects ion release rate
Oxidiser (Chlorine)
Ideal: 0.2-0.5 ppm
Minimum: 0.2 ppm
Test: Daily
Purpose: Burns off organics
Total Alkalinity
Ideal: 80-120 ppm
Test: Weekly
Impact: pH stability
Calcium Hardness
Ideal: 200-400 ppm
Test: Monthly
Note: Affects electrode life
Total Dissolved Solids
Maximum: 1500 ppm
Test: Quarterly
Action: Dilute if too high
Common Problems and Solutions
Troubleshooting Guide
- Green tinge to water: Copper levels too high - dilute pool water and reduce ioniser output
- Black staining: Silver deposits - requires professional treatment
- Cloudy water: Insufficient oxidiser - increase chlorine to 1 ppm temporarily
- Algae growth: pH too high or copper levels too low - adjust accordingly
- Hair turning green: Copper oxidation - immediately check and lower copper levels
- Rapid electrode wear: Calcium levels too high or pH consistently out of range
Is a Naked System Right for You?
Consider a Naked System If:
- You or family members have chlorine sensitivities
- You're committed to regular, detailed water testing
- You understand it's not maintenance-free
- You have the budget for higher setup and running costs
- You're willing to learn complex water chemistry
- You have access to professional pool service support
Avoid a Naked System If:
- You want a truly low-maintenance pool
- You travel frequently or have holiday homes
- You're not comfortable with technical equipment
- You expect a completely chlorine-free pool
- Your water source has high mineral content
- You're on a tight budget
Professional Insights
After years of servicing both Naked systems and traditional pools across Perth and Western Australia, here are some honest observations:
- Learning Curve: Expect 3-6 months to fully understand your system's quirks and requirements
- Professional Support: Most Naked pool owners require monthly professional service visits, adding $50-$100 to monthly costs
- Warranty Considerations: Copper staining often isn't covered under pool surface warranties
- Resale Impact: Some buyers view these systems as complicated - may affect property sale
- Climate Factors: Perth's hot summers require more vigilant monitoring than cooler climates
- Water Restrictions: During restrictions, inability to dilute water can cause serious problems
The Bottom Line
Naked Freshwater Systems can provide a more pleasant swimming experience with reduced chlorine exposure, but they're not the simple, carefree solution often advertised. They require dedication, ongoing education, and typically higher running costs than traditional systems.
Our Recommendation: If you're considering a Naked system, budget for professional monthly service for at least the first year while you learn the system. Many successful Naked pool owners continue with professional support indefinitely to ensure optimal water quality and prevent costly staining issues.
