Basic Filtration functions

Your pool filter has been designed as a highly efficient dirt collector; it is essential that you remove the dirt that accumulates. On the Above Ground Pools that are equipped with sand filtration a process known as "Backwashing" is used to clean the filter. Backwashing involves reversing the flow of water through the filter sand fir 1 - 2 minutes. This process removes dirt trapped in the filter sand, the dirty water is pumped to waste.

It is not possible to clean Cartridge filters by backwashing. Cartridge filters need to be physically removed before they can be cleaned. (Refer to your pool installation / operation manual).

How long should I operate my circulation system for?

Different pool manufactures specify different run times for filter systems. The general consensus from pool professionals is that to ensure high water quality you should run your pool filter system for at least 8 hours a day. You should increase this during peak summer months to at least 12 hours a day. If your pool is heated you will possibly need to operate the circulation system for longer periods to allow the heater to achieve the desired pool temperature. If your pool becomes green or cloudy you will need to filter the water continually and backwash daily until the problem has been remedied. Shortening your filtration cycle will usually prove to be false economy.

A key component on any swimming pool circulation system is a Time Clock. When setting your Time Clock it is worthwhile splitting the daily run time into at least two segments; e.g. If you decide to operate the circulation system for 10 hours per day you should split the 10 hours into 5 hours in the morning and 5 hours in the evening. You should avoid running the filter when the pool is being used.

As with all electrical equipment on your pool, the timer should be linked to A 30mA Earth Leakage Circuit Protector Device. (E.L.C.P)

Cartridge Filters

Cartridge filters, as opposed to Sand Filters, will sometimes be supplied on Above Ground Pools. Cartridge Filters have the advantages of being smaller, and cheaper than Sand Filters. However, Cartridge Filtration is not as efficient as Sand Filtration; if your pool is fitted with a cartridge filter and you repeatedly experience water quality problems you should consider upgrading to a Sand Filter.

If your pool experiences clarity problems you should use a clarifier to enhance the water performance of your pool filter. Very small particles of dirt suspended in your pool water will be too small to be caught by your pool filter, this often results in cloudy pool water. Pool water clarifiers work by attracting the small particles of dirt suspended in your pool water, as the smaller particles are clumped together into larger particles, your pool filter will be able to trap them. A multitude of pool water clarifiers is available from your pool dealer. Choose your pool clarifier carefully, in general, the tablet, granular and gel type Clarifiers available are not compatible with cartridge filters, instead use liquid types such as Fi-Clor Clear. It is essential that the cartridge elements are kept clean at all times. They should be removed, hosed down and perhaps soaked in a cartridge cleaner usually available at pool dealers. Wear rubber gloves when handling these products, they are highly concentrated. Cartridges should be soaked in a bucket overnight and rinsed before being re used. Don't be tempted to use a household cleaning product or put them in your dishwasher, this will do more harm than good. You should buy a spare cartridge element, this will prevent the filtration system being out of use when the original one is being cleaned. Cartridge elements should be replaced at the beginning of each season. Useful tip… To improve the quality of your pool water, run the filtration for 24hrs per day during the busy season (or as long as the manufacturer advises). The longer the filter is left running, the better the water quality.

Sand filtration. Larger above ground pools will incorporate a sand filter rather than a cartridge filter. Sand filtration is a more effective means of physically removing particles from the pool water. Your sand filter will incorporate a multiport valve. Your multiport valve controls the various functions of your filtration system. It is essential to understand it's various settings. A multiport valve will incorporate the following settings…

1. Filtration. This is the normal setting for your Multiport valve. Whilst the Valve is in this position, the pool water is drawn through the pump, passed into the top of the sand filter and pushed through the filter media (sand), trapping suspended mater. At the bottom of your sand filter is a set of "Laterals" these act as an under drain system and will allow the water but not the sand to return into the pool.

2. Backwash… Sand filters are designed to accumulate dirt. It is important that they are cleaned regularly. This process, commonly known as backwashing, should be carried out weekly. Backwashing involves reversing the flow of water through the filter for several minutes, or until the site glass shows clean water. During this process the water is automatically discharged to waste, taking the accumulated dirt with it. Before backwashing, ensure that the water in your pool is at least 50mm above the skimmer centreline. Never allow the water level to drop to more than half way down the simmer during normal operation.

3. Rinse. This setting should be used immediately after backwashing, but only for 10-20 seconds. The pool water follows the same path as when on "Filter", except the water exits to "waste" instead of returning to the pool.

4. Recirculate. This setting should be used if your filter is temporarily out of action or when the water is very green. It bypasses the filtration and simply moves the water around, This may be required to dissolve chemicals into the pool.

5. Waste Takes water from your pool, bypasses the filter and runs to waste. By using this setting when vacuuming a heavily contaminated pool, you will prevent your filter from becoming clogged. Also useful to dump water containing the very fine "dead Algae" dust that would normally pass straight through the filter

6. Closed Must only be used when the pump is shut off. Used to isolate the circulation system during maintenance.

Cleaning your pool

Your pool will need to be vacuumed and brushed at least once a week, twice during warm spells. Neglecting to clean your pool, even if it looks clean can result in water quality problems. Remember that prevention is far less costly than cure!

Vacuuming your pool


There is a wide selection of vacuum systems for swimming pools. The design of your pool will determine which is the best for your particular pool. If your pool is fitted with a cartridge filter you will probably have little alternative to using the "Venturi" type cleaner. If your pool is fitted with a sand filter and a relatively powerful main circulation, you should consider a "manual suction system" as the bare minimum for your pool. These are often part of the "add on kit" that can be purchased with the pool. Automatic pool cleaners are also an option for sand filters.
