FAQ’s (These are provided as a guide. Always call Aquablue pools if you are unsure)


Why is my pump making noise?

There are a number of reasons why pumps can become noisy and they are:

If the water level is low in the pool and can cause the pump to suck in air and eventually run dry. (See below) Ensure the pool is filled up above the skimmer line or where recommended by the pool shop.


The internal working parts of the pump could be worn resulting in a loud noise like a bearing sound (whirring). If this is the case it will need to be repaired. If you have a loud noise coming from the pump and it is leaking water then it is possible the bearings and main seal will need to be replaced.


Debris like a small pebble could be caught around the impellor, so it will need to be removed and checked for damage. Regular Maintenance can prevent these issues from occurring so contact us today and book a regular service. If your pump is making a noise..TURN IT OFF at the power point and call AQUABLUE POOLS.


What causes my pump to suck air?

Whilst there can be many reasons for this occurring it will normally have something to do with the pool cleaner, water level of the pool or the pump.


The pump lid (where you can see the water moving) could be cracked or the O’Ring which seals it may be worn out. Even a small piece of dirt or rock caught under the lid can stop the air tight seal. Either way you will hear a slurping sound indicating that air is being sucked in. If this occurs you should switch off the equipment and call your pool professional Aquablue Pools.


A cleaner hose may have a pin hole in it or be cracked a long one of the seams this can also get air into the pump. Check each hose to see if you can identify the hole or crack and replace the piece of hose when you can. The cleaner may also be leaping out of the water at times, this means it is running to fast and you will need to adjust the flow control valve to slow it down.


Check inside the skimmer box to ensure that the vacuum plate and flow control valves are covered with water. The third most common reason why the pump sucks air is that there is not enough water in the pool. If this is the case then you will need to put the hose in the pool and fill it up to the correct level. If you are unsure what the correct level is call your pool professional Aquablue Pools.


If my pump & skimmer baskets are full will it hurt my pump?

Yes! If the baskets are not regularly checked or emptied after a rain storm or periods of high winds then the baskets will become blocked and suction will be reduced and will cause the pump to burnout because of poor water flow. This will stop your pool cleaner and filter from working and eventually the pool will go cloudy and algae will grow, turning your pool green.

We suggest that baskets should be looked at once per week to ensure good water flow until your pool technician comes to complete your monthly service. Download our weekly maintenance tips for swimming pools.

What happens if my cartridge gets blocked for long periods?

A blocked cartridge will cause high water pressure and poor water return, it will also indicate poor suction so your auto cleaner won't work. Oils, lotions and calcium residues will also cause poor filtration and blocking of the cartridge. To ensure that your cartridge or sand filter is operating correctly contact your pool professionals at Aquablue Pools.


Why is the water level of my pool dropping?

If the water level in your pool seems to be dropping quickly there are a few steps you can take to check if it is within acceptable parameters. In the first instance check what the normal daily evaporation rate would be for the particular month you are in.

MEAN Daily Evaporation TAT (mm) – Sunshine Coast (approx)









Sunshine Coast









If the pool continues to drop at a fast rate you need to look for other problems like a

leaky pool liner, leaking or the multiport valve on the filter, water dripping or spurting out a valve or some of the plumbing. You could also have problems with your pump as it could be leaking or there could be a more serious problem of a cracked pipe underground.


Bucket Test

A simple test is to fill the pool to a level and remember what tile or mark it is at.

Fill a 10lt bucket and mark the water level when it is full.

Place the bucket beside the pool and leave them both for 24hours. If the pool and bucket go down similar amounts then it is unlikely there is a leak. If there is a big difference call your pool professionals Aquablue Pools immediately.

DOES NOT WORK IN THE RAIN or if you top the pool up during the 24 hour test.


Why is my pool cleaner not working or sucking properly?

Below is a list of general guidelines, for best results contact Aquablue Pools.




Pool cleaner stops and starts or does not run at all.

  • Check the skimmer & pump baskets are not full of leaves or debris.
  • Ensure that the vacuum plate is installed properly
  • Ensure the cleaner hose is not coming off the vacuum plate.
  • Check each of the cleaner hoses for holes, splits and debris stuck inside.
  • Check the diaphragm is not split or has a hole in it

There is no suction and the cleaner just sits there.

  • Backwash the sand filter and recheck the suction

Call Aquablue Pools

The pool cleaner is missing spots in the pool

  • Ensure that the correct amount of hose in installed. Try adding or taking away one or two hose lengths.
  • Ensure that all the returns are directing water flow towards the floor of the pool by adjusting the eyeballs.
  • Ensure the hose is straight and untangled. It helps to remove the hose from the pool occasionally and lay it out straight around the pool to take the memory.

The cleaner sticks in corners on the lights or on the steps

  • Ensure that the correct amount of hose is installed, try adding or taking off a length and retest.
  • Ensure that all the returns are directing water flow towards the floor of the pool by adjusting the eyeballs.
  • Excess water movement on the water surface will hold or push the hose into one place constantly.
  • Replace the wheel deflector with the biggest sized one available.
  • Change the hose weight by 4 inches (10cm) at a time,

up or down the cleaner hose. If the pool cleaner sits up put the weight closer to the head and vice versa.

The cleaner is loud and jumping out of the pool

  • The cleaner should not be loud and making strong ticking sounds. Gauge this by the ripples that come of the hoses that are on top of the water. They should only be slight and not making waves. Light ticking.
  • Turn down flow control valve until the cleaner settles.

The cleaner does not climb the walls

  • High PH or lack of chlorine can make the walls slippery so get the water balanced call Aquablue Pools.
  • Adjust the speed control valve to increase suction.



Why is there no chlorine in the pool?

There are any number of reasons why this continually occurs most times it will be something not right with the salt water chlorinator if you have one on your pool. If the chlorinator is not operating correctly then it will not produce chlorine and this can be because of low water pressure, dirty or broken cell, corroded terminals, broken control box, filter blocked or there may be low water in the cell due to blocked baskets or pipes or there may not be enough salt in the pool so call an Aquablue Pools technician to repair it.


For non salt water pools there may be a lack of chlorine because of high bather use, people using lots of sunscreen and jumping into the pool or maybe there is not enough stabiliser to help slow the process of chlorine going out of the pool. It may be that you need to increase the amount you put in regularly to meet demand.


There could also be high phosphate due to debris like leaves and dirt that can contribute to the consumption of chlorine. Overall it is best to get a pool professional out to have a look and get it fixed.




My pool has a bathtub ring...

Floating oils, dirt & waste can combine to form a scum line around the pool; this is why tile, an easily cleanable surface, is placed at water level around the perimeter of the pool. There are many tile cleanser products available which are applied with a scrubbing pad or brush and a little elbow grease. Abrasive cleaners work well, but should be avoided in vinyl lined pools. On vinyl pools use a vinyl cleaner such as Armour All Cleaner (not conditioner), and on Baquacil treated pools, use a cleanser made without chlorine.


Cleaning the scum inside of the skimmer frequently will help to keep the tile cleaner, as scum sticks itself to clean plastic. Using enzyme products can reduce or eliminate the amount of attention to the scum line as the work to "eat" scum producing substances.


The floor of my pool is covered in leaves.

Leaf removal can be hard work. At this stage, vacuuming through the skimmer or using automatic pool cleaners are very ineffective methods; both will clog up too quickly. The method of choice for the pool janitor is using a leaf rake attached to a telescopic pole. Slowly push the leaf rake along the floor, scooping up leaves into the bag. Work the pool in sections, trying not to create leaf-stirring currents. It takes practice but it can be very effective.


My pool has rubbish floating on top...

Check the main drain is clear of debris and empty the skimmer basket before you start. If you haven't purchased a leaf rake get one now. There are also chemical products which are used to keep surface tension high, moving small debris to the sides of the pool. Another possible problem could be the condition of the weir in the skimmer; you know, that flappy thing. Make sure it is operating properly so that it creates a draw or "waterfall" into the skimmer basket. Also check that the water level is not so high that it is above the opening of the skimmer. Overall you may need to get into gardening and remove some of the trees causing the issues.



What is the difference between automatic and robotic cleaners?

Automatic cleaners are terrific time-savers, and they also help to distribute and circulate the water while (some of them) decreasing the work load required of the filter. There is a wide range of cleaners available, for all types of pools and budgets. Suction cleaners start at around $99 through to $3000 however, between the $330-$400 mark gets you well established.


The more expensive robotic models will vacuum more debris, more efficiently and without compromising the filter system. Robotic cleaners don’t use a hose so there is no issue with trying to swim with it in the water. They use an 18m electric cable that regulates either 1.5 hours or 2.5 hour services on the pool. They will pick up a lot more than any suction cleaner does and they will climb the walls and clean them. They start at around $650 through to $8000 however a price between, $1300 - $2000 will get you well set up with plenty of warranty. 


Do I need to brush my pool regularly?

YES...Your pool brush attaches to the telescopic pole, and is most commonly used to brush algae off of the walls. By brushing your pool it will keep dirt from occupying the small pores and stop algae from forming in the pool. Steel bristled brushes, called algae brushes, are very effective on, you guessed it, algae. Do not use a steel brush on a vinyl lined pool.


Done regularly, brushing can also reduce the time spent vacuuming. Brush from the shallow end towards the deep end in overlapping strokes. Circle the pool towards the main drain, and much of the dirt will be swept up into the filter in this manner.


How do I vacuum my pool?

 Unless you have an automatic cleaner, robotic or an inbuilt system, then follow these simple steps:

Roll your vacuum hose straight along the length of the pool. Attach one of the cuffed ends onto your vacuum head which is attached to your telescopic pole. Extend the pole and place the head (with the hose attached) into the water so that it rests on the floor of the pool. Point the head across the pool so that it doesn't roll down the slope towards the deep end and prop the pole up against the pool's edge.


From the point where the hose surfaces, begin pushing the hose straight down into the water, hand over hand, until you reach the other end. This is filling the hose up with water so there is no air in it which may cause difficulties for the pump when you attach the hose to the skimmer. Another method of "priming the hose" is to hold the cuffed end firmly over a return fitting to force the air out of the end attached to the vacuum head.


Once the hose is primed, remove the skimmer lid and the basket and stick the hose end into the hole at the bottom of the skimmer. If it sucks it in tightly, great. If not, you may need a threaded hose adapter to achieve a tight fit. Now, the suction that was at the hole is now at the vacuum head. Do not lift the head out of the water with the hose attached, or you will fill the hose with air, losing prime, and possibly drawing air into the pump.


Roll the vacuum head on the floor, over the debris, now you're vacuuming. The suction will gradually decrease as the pump basket fills with vacuumed debris. When the pressure gauge drops and/or suction is sufficiently decreased, stop the pump and empty the basket. If pressure rises significantly, stop the pump and backwash the filter. Continue in this manner


My tiles have a crusty white deposit on them..

Calcium deposits usually originate from grout or setting mortar. To remove, scrape it off the tile/wall, and/or acid wash it. There are products available such as CLR (Calcium, Lime, Rust remover), which can be purchased at your local hardware store, will work well for such tasks. Another method for removing calcium deposits is the pumice stone. Pumice is a light porous glassy lava stone that can be rubbed over a pool stain to remove it. You can get a pumice stone that can attach to your tele-pole or a pumice stone that has a handle you can swim with. 

My pool is stained!

Dirt, leaf tannins, rust and other minerals can stain the finish of your pool. If the stain is organic; left from a leaf or palms for example, a small amount of granular chlorine added at that location and allowed to settle on the stain will usually remove it instantly. Other non-organic stains will not be removed by chlorine. Do not place chlorine tablets directly into the pool...they will stain and etch the finish.


If chlorine doesn't work, acid usually will. Draining and acid washing will remove a thin layer of plaster (and stains), exposing fresh, new looking plaster beneath. A No-Drain acid bath can also be performed, with varying results. The are other chemicals that can be used to treat stains but ask your pool professional as soon as you notice staining. The longer you leave it, the harder it can be to get rid of.


How do I backwash my filter?


1.Turn pump OFF and position handle to "BACKWASH".
2.Start pump and operate for 60 seconds or until the water is clear in the discharge sight glass.
3.Turn pump OFF and position handle to "RINSE".
4.Start pump and operate for 20-30 seconds.
5.Turn pump OFF, position handle to "FILTER".
6.Start pump, check clean filter pressure and resume Filtration Cycle.
Disconnect Pool Cleaner when backwashing the Filter.


FILTER - Normal filtration, water recirculated
BACKWASH - Reverses flow, cleans filter, water to drain
RINSE - Rinses and settles sand, water to drain
WASTE - Bypasses filter, water to drain
RECIRCULATE - Bypasses filter, water recirculated
CLOSED - Shuts off flow to filter
