How a salt chlorinator keeps your pool sanitised
A salt chlorinator turns mildly salty pool water into chlorine as it flows through an electrolytic cell. The chlorine does its work and reverts to salt, so you top up salt now and then instead of handling granular chlorine every week. The water feels softer and the chlorine smell is much milder than in a hand-dosed pool.
The Zodiac EI Classic Mini and Midi are matched to pool volume, so start with a realistic figure for your litres. Multiply length by average width by average depth in metres to get cubic metres; each cubic metre holds a thousand litres. Pick a unit rated a little above your pool rather than one working flat out through January.
Gauteng water is hard, and the cell is where that shows. Calcium settles on the plates as a white crust, chlorine output drops and the pool drifts slowly towards green even though the unit appears to be on. Holding pH in range slows the scaling, but every cell needs a periodic soak in a mild acid cleaner and, eventually, replacing.
- Test salt level and pH regularly; most chlorinator complaints begin with one of them drifting.
- Wire the chlorinator to switch with the pump so it never runs without water flowing.
- After heavy rain or a heatwave, raise the output setting rather than adding extra salt.
- Look into the cell for white scale whenever you empty the pump basket.
- Salt water is harder on old metal ladders and fittings, so check them for corrosion.
