Zodiac Ezi Saltwater Chlorinator | 24g/hr | Pools Up to 70,000L
Manually dosing chlorine is time-consuming, inconsistent, and easy to get wrong. The Zodiac Ezi 24g/hr Saltwater Chlorinator converts ordinary pool salt into a continuous, measured supply of pure chlorine, keeping your pool sanitised, balanced, and swim-ready with minimal effort.
The 24g/hr output is sized for pools up to 70,000L running 8 hours per day. For larger pools, see the Zodiac Ezi 40g/hr model which covers pools up to 100,000L.

Installation Guide
The Zodiac Ezi installs inline on your return line, after the filter and heater (if fitted). The cell must be installed horizontally or at a slight upward angle to ensure full water flow across the plates. Plumbing connections use standard 40mm barrel unions with no specialist tools required. Full step-by-step instructions are included in the owner's manual.
Important: Ensure your pump runs at least 6-8 hours per day for effective sanitisation. The required salt level is 4,500 ppm - check with Salt Pool Test Strips before and after adding salt.

Frequently Asked Questions
Q: How much salt do I need to add to my pool?
A: The Zodiac Ezi requires a salt level of 4,500 ppm for optimal operation. For a 50,000L pool starting from fresh water, you'll need approximately 225kg of pool salt. We recommend Pacific Premium Pool Salt, available in 20kg bags.
Q: How often does the cell need replacing?
A: With proper water balance and regular cleaning, a Zodiac Ezi cell typically lasts 3-5 years. The reverse polarity self-cleaning function significantly extends cell life compared to manual-clean cells.
Q: What salt level should I maintain?
A: 4,500 ppm for optimal chlorine production. Use Salt Pool Test Strips to check your salt level regularly.
Q: Can I use this with an existing pool pump?
A: Yes - the Zodiac Ezi works with any standard pool pump and filter system. It installs on the return line after your existing equipment. Ensure your pump runs at least 6-8 hours per day for effective sanitisation.

A: The built-in battery backup retains all settings and the clock during power outages, so your chlorination schedule resumes automatically when power is restored.
