Product Selection Guide

Industry accepted standards for water quality in swimming pools recommend that filtration equipment is able to turn over the entire body of water within these time periods.

Swimming pool Domestic: 6 Hours
Swimming pool Commercial: 4 Hours
Spa pool Domestic: 1 Hour
Spa pool Commercial: 1/2 Hour with a 1 hour filtration cycle after bathing

Actual operating time per day is dependant on debris load, number of bathers and sanitation
method.

Davey has made product selection easy by labelling their equipment with flow rates for
average operating pressures, and converted these with domestic swimming pools turnover
rates into a simple table.

To select the right equipment for your pool, follow steps 1,2,3 and 4

1. Calculate your pool volume.

Calculate your pool volume.

The formulae below requires all dimensions to be
in metres. If the depth of the pool varies, the
average depth should be used.

RECTANGULAR POOLS
length x width x depth x 1000 = volume in litres

ROUND POOLS
diameter x diameter x depth x 785.5 = volume in
litres.

Rectangular above ground pools.

4.9m x 3.7m x 1.2m = 22 000 litres
(16' x 12' x 4')

6m x 3.7m x 1.2m = 27 000 litres
(20' x 12' x 4')

7.3m x 3.7m x 1.2m = 32 000 litres
(24' x 12' x 4')

9.8m x 3.7m x 1.2m = 44 000 litres
(32' x 12' x 4')

5.8m x 4.5m x 1.2m = 31 000 litres
(19' x 15' x 4'

8.2m x 4.5m x 1.2m = 44 000 litres
(27' x 15' x 4')

9m x 4.5m x 1.2m = 49 000 litres
(30' x 15' x 4')

Circular above ground pools

3.7m x 0.9m = 10 000 litres
(12'x3')

4.5m x 0.9m = 14 000 litres
(15'x 3')

4.5m x 1.2m = 19 000 litres
(15' x 4' )

5.5m x 1.2m = 29 000 litres
(18' x 4')

6m x 1.2m = 34 000 litres
(20' x 4')

6.7m x 1.2m = 42 000 litres
(22' x 4')

Rectangular in-ground pools.

6m x 3.7m x 1.4m = 31 000 litres
(20' x 12' x 4'6")

7.3m x 3.7m x 1.4m = 38 000 litres
(24' x 12' x 4'6")

9m x 3.7m x 1.4m = 47 000 litres
(30' x 12 x 4'6')

9m x 4.5m x 1.4m = 57 000 litres
(30' x 15 x 4'6")

12m x 4.5m x 1.4m = 76 000 litres
(40' x 15' x 4'6")

12m x 6m x 1.4m = 101 000 litres
(40' x 20' x 4'6")

15m x 7.5m x 1.4m = 158 000 litres
(50' x 25' x 4'6)

1.4m (4'6") = average depth

2. Selecting the right size pump or filter

In ground swimming pools

Pool Volume	Power Ace CR Pumps	Power Master Pumps	Crystal Clear Sand Filters	Easy Clear Cartridge Filters
30 000 l	PA CR 100	-	CC180
45 000 l	PA CR 150	-	CC 180	EC 500
70 000 l	PA CR 200	PM 200	CC240	EC 700
90 000 l	PA CR 300	PM 250	CC330	EC 1000
110 000 l	PA CR 300	PM 350	CC 400	EC 1500
160 000 l	-	PM 450	-	EC 1500

Note: It is possible to use larger sized cartridge filters to minimise the element cleaning required.

Above ground swimming pools

Pool Volume	Power Ace CR Pumps	Power Master Pumps	Crystal Clear Sand Filters	Easy Clear Cartridge Filters
40 000 l	PA CR 100	PM 100	CC 180	EC 500
50 000 l	PA CR 150	PM 150	CC 180	EC 750

3. Selecting the right filter type

	Sand Filter		Cartridge Filter
	Sand	Zelbrite
Filtration Clarity	good	excellent	very good
Smallest particle removal	15-20	3-5	5-10
Media Type	granular media which is re-used for several years	granular media which is re-used for several years	Mesh element which is regularly cleaned and replaced after 3-5 years
Cleaning method	Backwash - reverse flow of water through filter to flush out dirt	Backwash - reverse flow of water through filter to flush out dirt	Remove element and hose down. Acid wash once a year.
Loss of pool water	Yes, due to backwashing	Yes, due to backwashing	No, as backwashing ************
Ease of operation	Very simple, as the media is not handled and is re-usable	Very simple, as the media is not handled and is re-usable	Requires more attention as the element should be removed and *****
Operating cost	Low, as media is virtually permanent	Low, as media is virtually permanent	High, as elements are relatively ********
Initial cost	Medium	Medium	Low

Difference Between Filters

Sand filter with Sand - 20-15 micron

Cartridge filter - 7 micron

Sand filter with Zeolite - 1 micron

D.E. filter - 5 micron

*THE DIFFERENCE BETWEEN FILTERS*
The difference between sand and cartridge filters is basically a choice between water saving, and water clarity.

For example; 1 micron being the clearest water.

Sand Filter with Sand media :15-20 micron

Cartridge Filter: 7- 10 micron

D.E Filter: 5- 7 micron

Sand Filter with Zeolite media - 3 micron

Basically, you have 2 choices in Filtration.
A) Water Clarity & B) Water Saving

A) WATER SAVING FILTRATION
FILTER CARTRIDGE - DAVEY EC SERIES
CARTRIDGE - DAVEY SILENSOR SERIES( SUPERQUIET)
SALT WATER CHLORINATOR - DAVEY SC SERIES (DIGITAL SELF CLEAN)
POOL BLANKET & ROLLER - (50% SAVING ON WATER EVAPORATION)

B) WATER CLARITY FILTER
FILTER CARTRIDGE - DAVEY CC SERIES (SAND FILTER)
CARTRIDGE - DAVEY SILENSOR SERIES( SUPERQUIET)
SALT CHLORINATOR - DAVEY SC SERIES (DIGITAL SELF CLEAN)
ZEOLITE - MINERAL FILTER MEDIA (POROUS 1 MICRON)
NATURE 2- MINERAL DISPENSOR (REDUCES CHLORINE)
POOL BLANKET & ROLLER - (50% SAVING ON WATER EVAPORATION)

Recommended Chemicals For Pristine Water Clarity
# Super shine
# Gel cube
# Starver
# Clarifier

4. Selecting the Right Sized Chlorinator

The appropriate chlorinator size for your pool is dependent on the local climate and the amount of use the pool gets. Note that chlorinator cell life can be increased with shorter running times during winter and lower output settings. Davey recommends that a chlorinator is run for between 6-8 hours a day during summer and between 2-4 hours during winter. A 24 hour super-chlorination after heavy use is also a good idea.
