Section 4. Pool Water
Preparation
4.1 Determining Pool Size (Litres of
Water in Your Pool)
• Rectangular Pools
Average length (metres) x average width (metres) x
average depth (metres) x 1000 = litres capacity.
Circular Pools
•
Diameter (metres) x diameter (metres) x average
depth (metres) x 785 = litres capacity.
• Oval Pools
Long diameter (metres) x short diameter (metres) x
average depth (metres) x 785 = litres capacity.
Sloping Sides
•
Multiply total litres by 0.85 = litres capacity.
4.2 Determining Pool Size (Gallons of
Water in Your Pool)
• Rectangular Pools
Average length (feet) x average width (feet) x
average depth (feet) x 7.5 = gallon capacity.
• Circular Pools
Diameter (feet) x diameter (feet) x average depth
(feet) x 5.9 = gallon capacity.
• Oval Pools
Long diameter (feet) x short diameter (feet) x
average depth (feet) x 5.9 = gallon capacity.
Sloping Sides
•
Multiply total gallons by 0.85 = gallon capacity.
WARNING
Heavy pool usage and higher temperatures may
require higher chlorine output to maintain proper free
chlorine residuals.
High Water Temperatures: Because chlorine
demand increases with the rise of water temperature,
adjustments must be made in order to keep up with
chlorine demand. In hot summer months, where the
water temperature rises above 30ºC (85ºF), you must
increase the pump run time and increase the chlorine
production (%).

ENGLISH
Heavy Bather Loads: Because of heavy bather loads, it
may be necessary to use a dichlor product registered or
scheduled under the Pest Control Products Act (PCPA)
to maintain an appropriate chlorine residual in the water.

Chemistry You Need to Know

Chlorine Stabilizer for Outdoor Pools (cyanuric
•
acid) is needed to maintain proper levels of
chlorine. Most unstable chlorine is destroyed by
the UV radiation from the sun within two (2) hours.
Chlorine stabilizer should be maintained between
30-100 ppm. For indoor pools, it is not necessary to
add chlorine stabilizer to the swimming pool water.
Nitrates can cause extremely high chlorine
•
demands and will deplete chlorine from your
swimming pool. In some cases nitrates may even
lower your chlorine levels to zero. Your local
qualified service representative can test for nitrates.
Make sure nitrates are not present in your pool.
• Metals (some metals) can cause loss of chlorine.
Also, metals can stain your pool. Have your local
qualified service representative check for metals and
recommend methods of removal.
• Chloramines should not be present in pool
water. When organic materials combine with free
chlorine, chloramines are formed. This ties up the
free chlorine in your pool and does not allow the
chlorine in your pool to disinfect. Chloramines
also cloud pool water and burn the eyes. Shock to
remove chloramines at the initial startup of the pool.
• Super Chlorination burns out the organic material
that has combined with chlorine. This frees the
chlorine for sanitizing. When experiencing heavy
swimming loads or heavy rainfall, use the Boost
mode to maximize chlorine production.
Shocking (Superoxidation) is also a means of
•
burning out the organic material that has combined
with chlorine. This method involves the manual
addition of chemicals to quickly raise the level of
chlorine. When the chlorine level is quickly raised
to 5 - 15 ppm the pool water is said to have been
shocked.
NOTE On initial startup of a pool, it is best to shock
using a dichlor product registered or scheduled
under the Pest Control Products Act (PCPA).
