Preparing Your Pool for Summer in Queensland

Preparing your pool for summer in Queensland is worth doing properly — and worth doing before the season arrives rather than on the first hot day when the kids are already in their swimmers.
Queensland summers are long and the pool gets serious use from October through April. A pool that hasn't been properly prepared can spend the first weeks of summer fighting chemistry problems, running equipment that's due for a service, or dealing with maintenance issues that a little attention in September would have prevented entirely.
This is the complete preparation checklist — everything to work through before the season starts.
Start With the Equipment
The pool's mechanical and electrical equipment works hardest through summer. Before the season starts is the right time to identify anything that needs attention — not mid-January when a pool technician's availability is stretched and your pool is sitting green.
The Pump
Run the pump and listen. An unusual noise — grinding, rattling, high-pitched whine — indicates a bearing or impeller issue that will worsen under the extended summer run times. Check the pump strainer basket. Clean it. Inspect the lid O-ring and lubricate it with silicone lubricant if it's dried or cracked.
If the pump is more than 8 to 10 years old and hasn't been serviced recently, a pre-summer service by a pool technician is worthwhile. A pump failure in the middle of summer is more disruptive and more expensive to resolve than a service in spring.
The Filter
A sand filter should be backwashed and rinsed before summer. If the sand hasn't been replaced in the last 5 to 7 years, pre-summer is a good time to do it — old, clogged or channelled filter media reduces filtration efficiency significantly. A cartridge filter should have its cartridges cleaned or replaced. A DE filter should be cleaned and recharged.
After the filter service, run the system and check that the pressure gauge reads within the normal operating range. High pressure indicates a dirty or blocked filter. Low pressure can indicate a suction-side problem.
The Chlorinator
Salt chlorinators are the most common sanitisation system for Queensland residential pools. Before summer, inspect the salt cell — the electrode housing that converts salt to chlorine. Scale buildup on the electrode plates reduces chlorination efficiency.
Clean the salt cell with a dilute hydrochloric acid solution if scale is present. Some cells have self-cleaning cycles — run one and inspect the result. Test the cell's output by running the pool normally and checking chlorine levels against the cell's stated output. If the cell is producing significantly less chlorine than rated, it may be nearing the end of its serviceable life. Salt cells typically last 5 to 7 years.
Check the chlorinator's flow sensor, which tells the system whether water is flowing before it activates the cell. A faulty flow sensor can prevent the chlorinator from operating even when the pump is running.
The Heater
If the pool is heated — whether by solar, heat pump or gas — inspect and test the heating system before the first cool evening you want to use it.
For solar heating: inspect the collector panels on the roof for damage, check the pipework connections and run the system through a full cycle. For a heat pump: run it through a full cycle and confirm it reaches setpoint. For gas: check the pilot or ignition, run a full cycle and inspect the connections for leaks.
The Lights
Test all underwater and perimeter lighting. Replace any non-functioning fixtures before summer. Underwater LED fixtures that are dimmer than they should be may have moisture ingress — a situation that requires fixture replacement before the issue affects the electrical system.
Clean the Pool Thoroughly
Before balancing water chemistry, the pool needs to be physically clean. Brush every surface — the walls, the floor, the steps, the tile line. A pool that hasn't been actively used through winter accumulates algae and scale at the waterline and develops areas of stagnation where the circulation doesn't reach.
Vacuum the pool floor thoroughly after brushing — the brushing dislodges settled debris and algae that needs to be vacuumed out rather than filtered. For significant algae growth, vacuum to waste rather than through the filter to prevent filter overloading.
Clean the tile line at the waterline with an appropriate tile cleaner. Scale and organic staining at the waterline is easier to clean before summer — before weeks of use bake it onto the surface.
Test and Balance the Water
Water chemistry that has drifted through winter needs to be brought back into range before summer use begins. Start with a full water test — ideally a professional test at a pool shop rather than a basic home test kit, which gives more accurate readings across a broader range of parameters.
The key parameters and target ranges:
Parameter | Target Range |
pH | 7.2 – 7.6 |
Total Alkalinity | 80 – 120 ppm |
Calcium Hardness | 200 – 400 ppm |
Free Chlorine | 1 – 3 ppm |
Salt (salt pools) | Per chlorinator manufacturer specification |
Cyanuric Acid (stabiliser) | 30 – 50 ppm |
Phosphates | Below 200 ppb |
Address total alkalinity first — it acts as the buffer for pH, and adjusting pH in a pool with out-of-range alkalinity is ineffective. Then adjust pH. Then check calcium hardness, which changes slowly and is corrected with calcium chloride (low) or partial water replacement (high).
Cyanuric acid — the stabiliser that protects chlorine from UV breakdown — degrades slowly over time. If your stabiliser reading is low, add stabiliser before summer. If it is high (above 80 ppm), the only correction is partial water replacement.
Phosphates are a food source for algae. Elevated phosphate levels make algae blooms more likely and harder to clear. A phosphate remover added before summer reduces this risk.
Check the Pool Shell and Surrounds
Walk the pool shell and look for cracks, lifting tiles, delaminating pebble, or staining that has developed over winter. Early identification means these issues can be addressed before they worsen through a full summer of use and temperature cycling.
Check the coping around the pool perimeter for cracks or movement. Check the surrounding paving for lifted or cracked tiles. Inspect the pool fence — particularly gate hardware. Test every gate to confirm it is self-closing and self-latching. A gate that has stiffened or failed to latch correctly is a non-compliance and a safety risk.
Check the pool cover if one is fitted — inspect the cover itself for damage and check the reel mechanism or housing.
Top Up the Water Level
Water lost through evaporation over winter needs to be replaced. The pool water level should be at the midpoint of the skimmer box opening — too low and the skimmer loses efficiency, too high and it is overwhelmed by debris.
Top up with a garden hose and monitor the time it takes. A pool that takes unusually long to fill — or that drops noticeably between top-ups — should be investigated for a leak. A leak test (turning off the pump and marking the water level, then comparing loss with pump running vs not running) distinguishes between a suction-side leak and a shell leak.
Shock Treat the Pool
Once the water chemistry is balanced and the pool is physically clean, a shock treatment — adding a large dose of chlorine — oxidises any remaining organic matter and chloramines and starts the season with a clean chemical baseline.
Follow the shock treatment with the filter running continuously for 24 hours. Test chlorine levels before anyone swims — the level should be back within the normal range (1 to 3 ppm) before the pool is used.
The Summary Checklist
Before summer starts, work through:
Pump: run, listen, clean strainer, inspect O-ring
Filter: backwash or clean, replace media if due
Chlorinator: inspect and clean salt cell, test output
Heater: full test cycle
Lights: test and replace as needed
Pool shell: brush and vacuum thoroughly
Tile line: clean at waterline
Water test: full professional test and balance
Coping and paving: inspect for cracks and movement
Pool fence: test all gates for self-closing and self-latching
Water level: top up to correct level
Shock treat: oxidise and run filter for 24 hours
A pool that goes through this checklist in September starts October ready. The first warm weekend of spring, the pool is clean, balanced and mechanically sound.

Pool showing its age heading into summer?
If the pre-summer inspection reveals issues beyond routine maintenance — a tired surface, ageing equipment, a pool that hasn't quite been right for a few seasons — it may be time for a renovation rather than another season of managing around the problems.
