Every spring we see the same story: a pool that was "fine when we covered it" in autumn is now green, the chlorinator cell is scaled solid, and the pump seal has perished from sitting dry. The repair bill often runs to hundreds of dollars — all avoidable with a light winter routine.
What actually happens to a neglected pool in winter
Brisbane winters are mild, which is exactly the problem. Your pool never fully "sleeps" — algae keeps growing slowly, leaves keep falling, and rainwater keeps diluting your chemicals. Meanwhile:
- Low chlorine + sunlight = algae. Even at 18°C water, algae blooms given a few warm weeks.
- Unbalanced water attacks surfaces. Low pH etches pebble and plaster; high pH scales your chlorinator cell.
- Idle equipment perishes. O-rings dry out, seals crack, and robotic cleaners hate sitting in chemically unbalanced water.
The 20-minute winter routine we recommend
- Run the pump less — but don't stop. 4 hours a day is plenty for most bayside pools in winter.
- Test fortnightly. Bring a sample in for our free computerised test, or use your own kit. Keep chlorine at 1–2 ppm and pH at 7.2–7.6.
- Empty baskets weekly. Winter winds fill skimmer and pump baskets fast.
- Keep the robotic cleaner running. A weekly cycle keeps the floor clean and the robot's seals healthy.
- Check the chlorinator cell monthly. If you see white scale, bring it in — a quick clean now beats a replacement later.
Money-saving tip: A winter service visit typically costs far less than one green-pool recovery in September. Most recoveries need multiple chemical treatments plus labour.
When to book a winter service
If you'd rather not think about it, book a one-off or monthly winter service. We'll balance the water, inspect the pump, filter, chlorinator and cleaner, and flag anything likely to fail before summer. You'll also beat the spring rush — our September calendar fills fast.
Winter is also the best time for equipment upgrades. Variable speed pumps, new chlorinators and heat pumps can all be installed now so you're swimming the day the weather turns.
The bottom line
Winter pool care isn't about doing more — it's about doing a little, consistently. Twenty minutes a fortnight, or one quick service visit, keeps thousands of dollars of equipment healthy and your water ready for the first warm weekend.
