If you’re a pool owner tired of buying chlorine every week or dealing with red eyes and dry skin, you’ve probably wondered: Should I convert my chlorine pool to saltwater?
Saltwater pools are growing in popularity across Australia — and for good reason. They’re often seen as easier to manage, gentler on skin, and cheaper to run long-term. But are they right for every backyard?
In this guide, we break down the pros, cons, costs, and steps to help you decide if switching to salt is the right move for you.
How Saltwater Pools Work
A saltwater pool still uses chlorine — but in a different way.
Instead of manually adding chlorine, you install a salt chlorinator. This system converts dissolved salt in the pool water into chlorine through a process called electrolysis. The chlorine sanitises your pool, then turns back into salt and is reused.
This system creates a closed-loop cycle that:
-
Maintains a steady chlorine level
-
Reduces the need for chemical dosing
-
Makes water feel smoother and softer
Pros of Converting to Saltwater
✅ Lower Maintenance
Once set up, saltwater systems automatically produce chlorine. This means less frequent chemical dosing and more consistent sanitising.
✅ Gentler on Skin and Eyes
Many swimmers find saltwater pools feel “silky” and less irritating. They don’t smell like strong chlorine and are better for sensitive skin.
✅ Fewer Harsh Chemicals
You’ll use fewer chemical additives over time. The water is sanitised with chlorine, but without the spikes or drops common in manually dosed pools.
✅ Cost Savings Over Time
Though the upfront cost is higher, you’ll save on weekly chlorine and other sanitiser products. The system pays itself off in the long run.
Cons of Converting to Saltwater
❌ Higher Upfront Cost
You’ll need to buy and install a salt chlorinator (and sometimes upgrade your pool pump). This can cost $1,200 to $2,500 depending on pool size.
❌ Potential Equipment Corrosion
Salt is mildly corrosive. If not properly maintained, it can damage metal fixtures, heaters, or poor-quality pool equipment.
❌ Ongoing Cell Maintenance
The chlorinator cell needs to be inspected and cleaned regularly. It also wears out over time and needs replacing every 3–7 years.
Is Your Pool Suitable for Saltwater?
Most in-ground pools can be converted without issue. But check the following:
-
Pool type: Concrete, fibreglass, and vinyl liner pools are all suitable with proper care
-
Pump and filter: These should be in good condition. Older systems may need upgrading
-
Fittings and fixtures: Check if your heater, lights or metal components are salt-compatible

How to Convert to Saltwater (Step-by-Step)
Step 1: Choose the Right Salt Chlorinator
Pick one that suits your pool size and usage. Look for brands with:
-
Self-cleaning cells
-
Digital displays
-
Low salt level alerts
-
Australian warranty support
Step 2: Install the Chlorinator
A licensed pool technician or electrician should handle the installation. The system is usually installed after the filter in the plumbing line.
Step 3: Add Pool Salt
You’ll need about 4,000 ppm of salt (roughly 200–250 kg for an average 50,000L pool). Use pool-grade salt only — not table salt or rock salt.
Step 4: Run and Monitor the System
Turn on the chlorinator and let it circulate. Monitor the chlorine output for the first week and adjust settings to match usage.
Step 5: Maintain the Cell
Clean the cell every 3–6 months to remove scale. Replace every few years based on manufacturer guidelines.
Cost Comparison: Chlorine vs Saltwater
| Expense | Chlorine Pool | Saltwater Pool |
|---|---|---|
| Weekly chlorine dosing | $10–$25/week | $0 (self-generated) |
| Salt chlorinator | $0 | $1,200–$2,500 (once-off) |
| Cell replacement (5 yrs) | $0 | $300–$800 (every 3–7 yrs) |
| Annual chemical costs | $600–$1,000 | $100–$300 |
Over 5 years, saltwater can save $1,000–$2,000 depending on usage.
Pool Maintenance Still Matters
Even with a salt system, you still need to:
-
Test water weekly
-
Adjust pH and alkalinity
-
Clean filters and baskets
-
Monitor calcium and stabiliser levels
We recommend stocking up on essential pool products like test kits, salt, pH adjusters, and clarifiers to keep your pool healthy and balanced.
Conclusion
Converting your chlorine pool to saltwater is a smart choice for many Aussie pool owners — especially if you want gentler water, lower long-term costs, and easier day-to-day maintenance.

Frequently Asked Questions
Yes — but it’s made automatically from salt through a salt chlorinator. This means you don’t need to manually add chlorine each week, and the water stays sanitised continuously.
The upfront cost is higher, usually $1,200–$2,500 for a salt chlorinator and installation. However, you’ll save money over time on chemicals and maintenance.
Not if it’s properly maintained. Most modern pool gear is salt-compatible. Make sure to clean the cell regularly and rinse metal fixtures with fresh water. High salt levels or poor-quality parts are more prone to corrosion.
For an average 50,000L pool, you’ll need about 200–250kg of pool-grade salt to reach the ideal salt level of 4,000 ppm. Always check your chlorinator’s specifications.
Yes. Saltwater pools tend to be gentler on skin and eyes because they avoid harsh chlorine spikes. The water feels softer and doesn’t have the strong chemical smell.
Not much. Just clean the cell every few months and replace it every 3–7 years. Most systems have self-cleaning functions and alerts to help you stay on top of maintenance.
Yes, it’s reversible. If you ever want to return to manual chlorine dosing, just stop using the salt system and treat your pool as you would a traditional chlorine setup.
No. You’ll still need to monitor and adjust pH, alkalinity, and other levels. But you’ll use fewer harsh chemicals overall, and the chlorine is produced consistently by the system.
Your chlorinator will alert you, and chlorine production will drop. You’ll need to add more salt to return to the ideal range. Low salt can result in cloudy or unsanitised water.
