Top 5 commonly asked questions
Q1. How long should I run the pool pump?
Q2. How often should I test the water balance?
Q3. What should the water level be kept at?
Q4. How often should I backwash?
Q5. How often should I clean the skimmer basket and the pump’s filter basket?
A1. Generally 4 hours a day in winter and 8 hours a day in summer
A2. At least once a week with your pool test kit and bring a sample to our store for testing once a month
A3. Half way up the skimmer box is optimum.
A4. Once a month for sand filters. It depends on the dust/debris that gets in and the time spent to skim, brush and vacuum. Filter type is also important.
A5. Ideally clean the skimmer basket daily and the pump’s filter basket once a week. Keeping the filter baskets free of leaf litter and debris improves the pumps efficiency.
Talk to us for specific advice about your pool
Pump running time depends on the size of the pool water to be circulated and the weather.
Water balance is vital to the health of your pool so do keep on top of it.
Keep an eye on the water level as the temperature and evaporation increases. Also check after rain.
If the pump pressure gauge starts to go up, this tells you that the filter needs cleaning by backwashing.
Minimise the frequency of filter basket cleaning by keeping your pool surrounds clear of vegetation and debris. Increase basket checking if it is windy.
Why is correct water balance so important?
Water balance tips
Bring a water sample to our store for professional testing each month
Use a home test kit weekly for small chemical adjustments. Also check after rain.
Problems if water is not balanced
If water is too acid (pH low), sanitisers (eg chlorine) don't work properly so:
If water is too basic (pH high), scale can build up on and damage equipment (pipes, heaters, liners)
Most equipment manufacturer's warranties do not cover damage due to low or high pH
Why is my pool is green? How do I fix it?
Green algae is a microscopic plant that grows when pool water:
Steps to kill algae
Shocking Do's and Don'ts
Chemical treatments work best if water pH is ok
Always pre-dissolve chlorine shock in buckets of water
Optional - Water clarifier can help filter the algae out of cloudy pool
Get advice for yellow or black algae - multiple shock treatments and algaecide may be needed
Do not use pool robots or automated vacuum cleaners until the pH of the water is acceptable

Why do we recommend quality chemicals?
Quality chemicals are fit for purpose and comply with quality and safety standards.
We stock and recommend:
The high cost of cheap chemicals - Example
Cheap salt often contains impurities. This can make your pool cloudy or cause staining.
Is saving a dollar or so on a bag of cheap salt worth it?
To remove the impurities, you will need to filter your pool for an extended period!
To remove stains from poor salt, you can use Focus products.
How often to test water
Use a home test kit weekly for small chemical adjustments.
Also check after rain.
Bring a water sample to our store for professional testing each month.
Add chemicals in small amounts to avoid chemical bounce.
How and why to winterise your pool?
Training and support
Contact us for advice on techniques or chemical amounts. We would be happy to winterise your pool for you or to demonstrate what to do.
Steps to winterise
What you need and why
Use a test kit and add acid to adjust pH to 7.2 to 7.6 and/or add buffer as needed
Chlorine shock kills and prevents algae growing
Select an algaecide appropriate for your pool
Decreasing filtration hours reduces electricity costs
Salt increases conductivity and assists chlorinator cell to maintain sanitiser levels
It is important to move water through the solar heating pipes daily to prevent algae
A pool cover helps keep debris out of the pool and prevents water loss. It can also trap chemicals so regular chemical checks are needed.
Maytronics Dolphin maintenance tips
Tips when using your robot
Only use the robot when the pool water parameters are correct (pH 7 to 7.8, salt < 5000ppm, chlorine < 4ppm, 6 to 34 degrees C )
When the robot is lowered into the pool, check that:
When working, keep the power supply in the shade and at least 3m from the pool's edge. Never use an electric extension cord.
Tips when putting your robot away
Wash the filters and reinsert the clean filters into the cartridges while the filters are still wet. Do not let the filters dry out while dirty.
Rinse the cleaning brushes with clean running water after each use.
Every 6 to 12 months, remove the cleaning brushes and wash them thoroughly.
Check that the impeller is free of debris or leaf litter.
Tips for extending the life of your robotic cleaner
Never lift the robot from the pool by its cable – lift it using the handles.
After each cleaning cycle, take the robot out of the pool to minimise wear on the plastic parts.
When not in use, store the robot on its Caddy: out of direct sun, excessive heat and frost.
Use an outdoor chair cover to protect the robot and power supply from dust and the elements.
Reset the full filter bag indicator on power supply to show correct status. Empty and clean cartridges. Put robot in the pool. Press Reset button while the robot is going.
Steps to minimise costs
If baskets are clogged with leaves, the pump has to work harder and is less efficient
Skimming leaves from the surface prevents debris sinking to the bottom where it is harder to remove
Water testing often and using small doses minimizes chemical bounce and the chemicals needed. Quality chemicals are fit for purpose and comply with quality and safety standards
Pool and spa safety
Registration and Inspection Requirements
Storing chemicals safely
Adding chemicals safely
Chemicals can be very dangerous if not used or stored properly
Incorrect use can cause fires, explosions or serious injuries
Carefully follow the manufacturer's labels and instructions
If uncertain, contact us or the manufacturer for advice.
Keep chemicals locked away and out of reach of children
Store chemicals in a clean, cool, dry, well-ventilated area
Never allow pool chemicals to mix with:
Don't stack different chemicals on top of one another
Don’t combine chemicals from new and old containers
Keep liquid chemicals away from dry chemicals
Store liquid chemical containers in a plastic crate to contain spills or leaks
Keep the original lids on all chemical containers
Ensure the lids are closed tightly when chemicals are put away
Do not store chemicals near a heat source such as the pool heater
Add chemicals to water. Never add water to chemicals
Add each chemical to the pool separately
Always add chemicals directly into the pool water, either spread across the pool surface, or diluted then poured into the pool or via a dispenser
Always have your pump on when adding chemicals
Allow time for one chemical to disperse before adding another chemical
Filter the water after adding a chemical - follow manufactures instructions
Use a clean and dry scoop for each chemical
Don’t use metallic utensils - use glass, plastic, or porcelain utensils

Wear eye protection and gloves
Wash off any chemicals that get on your skin or clothes immediately
If a chemical gets into an eye:
Only buy quantities you can use within the use-by dates
If disposing of chemicals, never combine incompatible chemicals in a bin
Follow manufactures instructions to dispose of empty containers.
Dogs in the pool – not recommended
Problems for pools
Dogs can bring dirt, body oils and faecal matter (stuck to fur) into pools affecting pH and creating a significant sanitiser demand
Many dogs shed hair which can end up in the skimmer and pump baskets, and in media filters increasing servicing and maintenance costs
An average sized dog is equivalent to 3+ humans in the pool and introduce germs such as E.coli, Giardia, Hepatitis A and Crytosporidium
Home pools only turn over the full volume of water about every 24 hours and germs can multiply rapidly in warm water in summer
Problems for dogs, owners and kids
Many pets drown each year in backyard pools. Most drownings are pups or dogs not trained in how to exit a pool or old /weak dogs that have unsupervised access to the pool.
Water born pathogens are quite contagious. Kids do swallow pool water or if scratched by a dog’s sharp nails can get an infection.
Dogs, like humans, can get skin irritations, dry skin, itching, red eyes and ear infections from pool water
If your dog drinks too much pool water it can make them ill
If you must let Fido swim…
Brush the dog to minimise hair loss in the pool
Wash the dog before and after it goes into the pool
Dry the the dog’s ears and consider use of ear wash and a coat conditioner
Supervise and train the dog – don’t allow free access to the pool and ensure it knows how to exit the pool at the steps
Clean dog hair from the skimmer basket, pump basket and check the pump pressure
For heavy use/multiple dogs and children, and in hot weather, the pool may require chlorine shocking, backwashing and extra filtration time
10 Common Pool Maintenance Mistakes
1. Not checking pool chemistry often enough
Check weekly. Check after heavy rain. Minor adjustments prevent bigger issues.
2. Allowing pH (acidity) to get above 8.0
Above 8.5 chlorine is only 10% active.
Maintaining pH at 7.5 is optimum.
3. Not keeping alkalinity between 80-140PPM
Low or high alkalinity decreases sanitiser effectiveness.
4. Not keeping calcium levels in the correct range for your pool type
Check often in the swim season as evaporation and splash out decrease hardness levels.
Calcium imbalance can cause scaling or corrosion.
5. Not running the pump for long enough
Good water circulation through the filter is key to low maintenance.
6. Leaving too much debris in the skimmer basket or pool pump lint filter
Debris in the baskets decreases water circulation.
7. Not vacuuming and brushing walls often enough
Dirty floors and walls encourage algae growth which can lead to calcification on tiles.
Using a brush on walls and floors and vacuuming will save money on chemicals.
8. Allowing salt water chlorinator cells to become calcified
Calcified cells produce little chlorine.
9. Not checking water levels frequently in summer
High evaporation rates can drop the water level below the skimmer.
Inadequate water flow can damage the pump.
10. Adding contaminants to the pool
Not showering before use can add body oils and contaminants.
Pets add much more contaminants than humans.
After heavy pool use or heavy rain, consider adding a clarifier and chlorine.
