Salt Logic vs Zodiac Ei Classic vs Zodiac EXO IQ: Which Pool Chlorinator Is Best for Your Swimming Pool?
A saltwater chlorinator is one of the smartest upgrades for a residential swimming pool. Instead of manually dosing chlorine all the time, the system converts dissolved pool salt into chlorine automatically, helping keep the water clear, more consistent and easier to manage. Swemgat currently offers three strong options in this category: Salt Logic, Zodiac Ei Classic and Zodiac EXO IQ. All three automate chlorination, but they are aimed at different budgets, pool sizes and owner preferences.
The Quick Answer
If you want the blunt truth:
- Choose Salt Logic if you want a practical, service-friendly chlorinator.
- Choose Zodiac Ei Classic if you want a trusted brand-name chlorinator with straightforward controls and lower entry pricing.
- Choose Zodiac EXO IQ if you want premium features, smart connectivity and a more advanced chlorinator system.
1. Salt Logic Pool Chlorinator
The Salt Logic Pool Chlorinator is built for pool owners who want dependable chlorination without paying for smart-tech features they may never use. On Swemgat, it is available for pools up to 50 000L, 75 000L, 100 000L and 150 000L, which gives it a wider pool-size range than the Ei Classic and EXO IQ units.
Where Salt Logic stands out is in its practical design. Swemgat lists features such as power supply efficiency above 90%, automatic salt concentration and cell-function monitoring, low-salt alarm and shutdown, variable current-controlled chlorine output, and advanced self-cleaning reversal circuitry. The sealed cell is also designed for easier installation and replacement, with a clear housing for visual inspection and lower-cost simplified construction.
For buyers thinking long-term, Salt Logic’s replacement-cell pricing is a major selling point. That matters because cell replacement is one of the real long-term ownership costs of any salt chlorinator.

2. Zodiac Ei Classic Saltwater Chlorinator
The Zodiac Ei Classic Saltwater Chlorinator is the most straightforward brand-name option in this comparison. It is positioned as an entry-level to mid-range chlorinator for homeowners who want reliable salt chlorination without complex smart controls.
One of the reasons many pool owners will like the Ei Classic is that it keeps things simple while still covering the essentials well. Automatic reverse polarity to reduce calcium build-up on the cell, a clear cell housing for easy inspection, LED interface feedback, incremental chlorine output selection, and a Boost function for times when the pool needs extra sanitising after heavy use, rain or hot weather.
The detailed specs also make it easier to position accurately:
- Ei Classic Mini: 12 g/h chlorine output, 70W, up to 60 000L
- Ei Classic Midi: 20 g/h chlorine output, 110W, up to 100 000L

This is where EXO IQ separates itself.

Swemgat further notes that the optional Dual Link Module can automatically regulate pH dosing and chlorine production for more advanced water-balance control.

Which Pool Chlorinator Is Best for You?
Buy Salt Logic if:
You want a chlorinator that is practical, robust and easier to justify on long-term value. It is especially attractive if you have a larger pool above 100 000 litres, because the listed Salt Logic range goes up to 150 000L.
Buy Zodiac Ei Classic if:
You want a reliable chlorinator from a recognized brand, with self-cleaning operation, Boost mode and straightforward controls, while keeping upfront cost sensible.
Buy Zodiac EXO IQ if:
You want a premium system and are willing to pay more for smart control, remote access and higher automation potential.
Salt Requirements for All Three
Swemgat states that these chlorinators generally require an initial dose of about 25kg of pool salt per 5 000 litres of pool water. After that, only salt lost through backwashing, splash-out or waste-water removal usually needs to be replaced. In many cases, this is about 20kg every 6 months for a 40 000-litre pool, though salt test strips and the owner’s manual should be used to confirm actual needs.
Final Verdict
For most homeowners, the real decision comes down to this:
- Want the most affordable branded simplicity? Go Ei Classic.
- Want practical value and serviceability? Go Salt Logic.
- Want premium automation and app-based control? Go EXO IQ.
