Brisbane & Queensland Summer Pool Checklist
Heat, UV, afternoon storms and a pool full of kids: a Queensland summer is hard on pool water. Work through this checklist in spring and keep it handy until autumn.
South-east Queensland summers bring long, hot days, strong UV, high humidity and those classic afternoon storms. All of that changes your pool water fast. Chlorine burns off in the sun, algae loves warm water, and a single storm can dump leaves, dirt and a lot of rainwater into the pool.
Here's a practical spring-to-autumn checklist. Tick it off in September or October, then use the weekly and after-storm sections all season.
Spring start-up (do once)
- Work out your pool volume so every dose is accurate. Use our pool volume calculator and write the figure somewhere handy.
- Clean or service the filter. Backwash a sand or glass filter, or hose and soak cartridge elements, following the manufacturer's directions.
- Check the salt chlorinator cell for scale and clean it as the manual directs. Then check the salt level against the chlorinator's recommended range.
- Get a full water test, either at home or at your local pool shop: free chlorine, pH, total alkalinity, calcium hardness and stabiliser.
- Check the fence, the gate and the CPR sign. See pool safety below.
- Service your robot cleaner by checking the brushes, tracks, filter and cable or swivel. Charge a cordless robot fully.
Water targets for hot weather
| What | Target | Source / note |
|---|---|---|
| Free chlorine | 1.0–3.0 mg/L (ideal 2) | SA Health guidance for home pools |
| Free chlorine with stabiliser | At least 3 mg/L | NSW Health: outdoor pools using cyanuric acid |
| pH | 7.2–7.6 | SA Health |
| Stabiliser (cyanuric acid) | About 30 mg/L, no more than 50 mg/L | NSW Health |
| Salt | As specified by your chlorinator | Check your chlorinator manual |
SA Health recommends testing before use and at least once a day for pH and chlorine, and more often in hot, sunny weather or when lots of people are swimming. Don't swim if the chlorine or pH is out of range, or if the water is cloudy.
Every week in summer
- Test chlorine and pH several times a week (daily during heatwaves and holidays) and adjust as needed.
- Run the pump and filter long enough. NSW Health suggests at least 8–12 hours a day depending on use, and summer generally means the higher end. Raise the chlorinator output if your chlorine keeps dropping.
- Empty the skimmer and pump baskets.
- Run the robot cleaner, or vacuum, and brush the walls, steps and corners.
- Check the water level. Evaporation is high in summer, and a skimmer that sucks air can damage the pump.
- Check the filter pressure gauge and backwash or clean the filter when it rises above the manufacturer's recommended level.
After a storm
Afternoon storms are the biggest summer headache in Brisbane. Rain dilutes your chemicals, wind dumps debris, and runoff can wash in soil and fertiliser.
- Get the debris out fast. Scoop floating leaves before they sink, empty the skimmer and pump baskets, and run your robot. Under gum trees? See robots for leaves.
- Lower the water level if heavy rain has overfilled the pool, using your filter's waste setting or the drain method in your filter manual.
- Clean the filter if the pressure has jumped.
- Test, then rebalance. After a major storm or heavy use, SA Health recommends shock dosing to 10 mg/L free chlorine for at least an hour with the pump running. Take the robot out first, and don't swim until free chlorine falls back to 4 mg/L.
- Check the fence and gate. Wind and fallen branches can damage them.
Robot cleaner tips for summer
- Daily short cycles keep up with storm debris and summer pollen better than one long weekly run.
- Rinse the filter after every run. A clogged filter is the most common reason a robot stops climbing walls.
- Store the robot and any charger or power supply out of direct sun when not in use. Manufacturers list storage temperature limits in their manuals.
- Remove the robot during shock dosing and check its water-chemistry limits in the manual.

Pool safety in Queensland
Summer is peak season for pool drownings, and Queensland has its own pool safety laws, administered by the Queensland Building and Construction Commission (QBCC). The rules cover things like pool barriers (fences and gates), CPR signage, registration of pools, and pool safety certificates in situations such as selling or leasing a property. Requirements change, so check the details for your property on the QBCC website.
- Make sure gates self-close and self-latch from any open position, and are never propped open.
- Keep climbable objects (pot plants, chairs, eskies, barbecues) away from the fence.
- Check that the CPR sign is in place and readable.
- Actively supervise children in and around water at all times.

How long should I run my pool pump in a Queensland summer?
NSW Health advises running pool filters at least 8–12 hours a day depending on use. In hot weather with heavy use, you'll usually need the top end of that range. Check your pump and chlorinator manuals, and consider off-peak tariffs if your electricity plan has them.
What should I do to my pool after a storm?
Clear leaves and debris, empty the skimmer and pump baskets, backwash or clean the filter if pressure is high, then test and rebalance the water. SA Health suggests shock dosing after a rainstorm or heavy use, then waiting until free chlorine is back down to 4 mg/L before swimming.
Do I need a pool safety certificate in Queensland?
Queensland has specific pool safety laws, including pool registration and pool safety certificates in certain situations, such as selling or leasing a property with a regulated pool. Check the current requirements with the QBCC.
