Salt Chlorinators

A salt cell doesn’t fail all at once — it fades, and the signs are easy to miss. The clearest one: your chlorine reading won’t hold, even a day or two after you’ve shocked the pool. Pull the cell out and there’s often a heavy white or grey crust across the plates — calcium scale that stops it generating chlorine properly, however hard it’s working. You might also notice you’re topping up salt more often, or the display’s throwing error codes it never used to.

Most cells are good for around 5–7 years with regular cleaning, less if the water’s been left to scale up. A dying cell is one of the most common reasons a ‘low-maintenance’ salt pool suddenly turns green — the chlorinator’s still running, it just can’t produce enough sanitiser to keep up. Caught early, a proper clean and salt chlorinator repair gets most Gold Coast cells back to full output. Left too long, it’s a straight salt cell replacement — we’ll tell you honestly which one you’re looking at before we touch anything.

This page is about keeping your existing chlorinator and cell clean, tested and working. For full new chlorinator installs, or unrelated pump, filter and plumbing repairs, that’s handled on our equipment repairs & installs page.
