Section 4. Pool Water Preparation

4.1 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.

4.2 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 790 = litres capacity.
• Oval Pools
Long diameter (metres) x short diameter (metres) x average depth (metres) x 790 = litres capacity.
• Sloping Sides
Multiply total litres by 0.85 = litres capacity.

4.3 Chemistry You Need to Know

• Chlorine Stabilizer (cyanuric acid) is needed to maintain proper levels of chlorine. Most non-stabilized chlorine
is destroyed by the UV radiation from the sun within two (2) hours. Chlorine stabilizer should be maintained
between 10 - 50 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 pool professional can test for nitrates.
Make sure nitrates are not present in your pool.
• Metals (some metals) can cause loss of chlorine stain your pool. Have your local pool professional 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 which frees the chlorine for
sanitizing. This is accomplished by raising the chlorine level quickly and dramatically. To super chlorinate the
pool using the Jandy
set the pump and the cell to run for 24 hours.
• 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 from an alternate source, i.e., use a shock treatment
available at your local pool supplier.
Never use dry acid to adjust pH in arid geographic areas with excessive evaporation and minimal dilution of pool
water with fresh water. A buildup of by-products can damage the electrolytic cell.
