Work out the size of salt water chlorinator that you need for your pool by working out the total litres of your pool using the following examples and then know your lowest ambient air temperature in your area and follow the guide under each product listing.
Volume of a Swimming Pool

The following is the procedure used to calculate the volume of a swimming pool.
Volume of a Swimming Pool
Volume = Length x Width x Depth

Example 1:
Pool Dimensions:
Length 25 metres
Width 10 metres
Depth 1 metres to 2 metres (average 1.5 metres)
Volume = 25 x 10 x 1.5 = 375 cubic metres
One cubic metre is equal to 1000 litres therefore the volume of the example above is 375 000 litres.
If the pool contains sections of different slope, the volume may be calculated by dividing the pool into sections each of which may be easily calculated. The final volume will be the sum of all the sections.

Example 2:
A pool has three sections:
Section 1 Section 2 Section 3
Length 10m Length 10m Length 5m
Width 10m Width 10m Width 10m
Depth 1m Depth 1-2m Depth 2m
Volume=100 cub. m + 150 cub. m + 100 cub. m
Total volume = 350 cubic metres or 350 000 litres.
