PPG Deluxe sand filter
The PPG filter Deluxe has a number of product strengths that allow this PPG sand filter to be called the Deluxe.
- At the top there is a large transparent lid with vent valve and pressure gauge that's held in place by an easy-to-screw collar, reinforced with fibreglass for maximum strength and durability. 
- The filter contains a large double drain stop. This makes it possible to discharge only water or water and filter media. 
- The sand filter includes a large, sturdy, industrial-quality base for stable floor mounting. 
- Inside, there is a large water diffuser and an easily accessible venting system. 

What do you put in the sand filter?
The delivery of the sand filter always includes the recommended amount of sand for the pool. You can put sand, glass filter media or flint in the sand filter. Sand and flint come in different sizes. To determine what and how much you should add to the sand filter, it's best to look at the paperwork of the sand filter. Sometimes there is a choice between glass or sand, in which case you can choose. 

The different settings of a swimming pool sand filter
A sand filter always has a 6-way valve, because six different modes of operation are possible with the sand filter. 
Please remember: If you change the mode, you should always switch off the pump! If you don't do this, your pump may be damaged. 

1. Filter: Filtering the pool water. The water goed via the pump to the sand filter. The clean, filtered pool water then exits the sand filter back into the pool. 
2. Waste (empty): This is to drain all the water out of the pool. This is only necessary when the pool is very dirty and needs a thorough cleaning. 
3. Backwash: ‘washing the water back'. This is to clean the sand filter. The water goes out in the opposite direction (into the sewer or another place). 
To backwash, you must first turn off the pump! Then first set the 6-way valve to backwash and switch the pump on. The water now flow in the opposite direction. Backwashing takes 1-3 minutes. If you look through the sight glass of the sand filter and the water is clear again, it's sufficient. 
4. Rinse: The six-way valve should be placed in this position immediately after backwashing. You do this for 30 seconds. On the rinse position, the water goes from the top to the bottom while it's discharged into the sewerage. In this way, all the sand is returned to its place. 
5. Circulate: This position is to mix certain products with the pool water as quickly as possible. The water is drawn in by the pump, but does not pass through the sand filter. 
6. Closed: Now all outlets are closed. You must now turn off your pump as quickly as possible, because the pressure builds up rapidly. The closed position is mainly used when working on the sand filter. 

In short, the 6-way valve is usually on the 'filter' position. 

How long do you have to filter the pool water?
The more your water is filtered, the better your water quality. This is very clear. 
But how long should your filter run?
Well:
If the outside temperature is less than 20°C, let the filter run for 12 hours.
If the outside temperature is more than 20°C, let the filter run for 24 hours.
Tip: Set the filter operating time with a clock. In this way, you can choose to let the filter run at night. 

Maintenance of a filter
Maintaining a cartridge filter
The neater the filter, the better the water can be filtered. 
It's recommended to clean a filter cartridge regularly with a cleaner for filter cartridges. With the nozzle cleaner you can already remove a lot of dirt from the filter. Ofcourse you can't keep rinsing the cartridge and it's recommended to replace the filter regularly. 
How many times you have to clean and replace the filter is hard to say. This depends on several factors, such as how often you swim, is there a tree in the neighbourhood, how is the water maintained,... It may ofcourse not be that the filter looks completely green or brown. Then the filtre has little effect on the cleaning of the water. 
Maintenance of a sand filter
A sand fitler requires a backwash (at least every three weeks, this may also be more) and after 5 years the sand in the filter must be replaced by new sand. 
If the sand filter has not been circulating for a long time, the sand will start to stick toghether and you will have to replace the sand. 
Besides backwashing and replacing the sand you should also put superflock plus in your skimmer. Superflock plus is a flocculant in the form of a candle that's used in sand filters for effective prevention and removal of turbidity in the water. Due to this pastented formula, superflock plus dissolves slowly, resulting in a long-term effect. Use superflock weekly for optimal results. 

Choose a filter to suit your pool
To know what filter capacity you need to filter your pool, you need to do a little calculation. I emphasise "small" because it doesn't take much time. You have to divide the amount of water by 4. This way, the pool is completely filtered in four hours. 
Calculation:
* Square or rectangular pool:
Lengh x width x height
e.g.: Length 8 m x width 4 m x 1.45 m = 46.40 litres of water = 46.40 m³
46,40 : 4 = 11,60
For the example given, you would need a filter pump with a flow rate of at least 11.60 m³/h. 
* Circular pool:
Radius x pi x height
(The radius is half the diameter e.g. diameter is 6, then the radius is 3.)
Example: radius 3 m x radius 3 m x pi 3.14 x height 1.50 m = 42.39 litres water = 42.39 m³
42,39 : 4 = 10,60
For the given example you would therefore need a filter pump with a flow rate of at least 10.60 m³/hour.

Types of filters
To filter your pool you can use two kinds of filters, a cartridge filter and a sand filter
cartridge filter:
A cartridge filter is easy to install and doesn't take up much space. A cartridge filter is also called a pattern filter and works with a filter pattern. The pool water goes through the filter cartridge and so the water is filtered. A filter cartridge is easy to replace and is low in price. When purchasing a cartridge filter, all accessories needed, such as water hoses, are included in the filter in one package. 
Sand filter:
A sand filter has better filtering characteristics and is cheaper than a cartridge filter, but it is a bigger investment. 
With a sand filter, the pool water enters the sand filter from above and sinks down through the sand. As the water descends along and between the sand, dirt from the water remains with the sand. This is how the water is filtered. 
Because the water descends via the sand, a lot of dirt remains in the sand after a while. In order to clean the sand, a backwash (rinsing) must be carried out. 
By performing a backwash (every three weeks), the dirty water is pumped through the backwash and the water goes to the sewer or to another drain. 
After 5 years, you should replace the filter sand with new sand. 
If the sand filter has not been circulating for some time, the sand will start to stick together and you will have to replace the sand. 
The amount and type of sand to be used in the sand filter is always indicated on the sand filter.

What should I add to my swimming pool filter?
To fill your sand filter, you should use sand, flint or glass. Depending on the filter, you should add sand, flint or glass. This can also be a combination of sand and flint. 
Which filter media you need to put in is always mentioned on your filter. For your swimming pool filter to work optimally, you should fill your sand filter with what is recommended.
