Looking After Your Above Ground Swimming Pool Water

19th May 2020

Looking After Your Above Ground Swimming Pool Water is achievable by adding chemicals to your water, this is necessary for a number of reasons; to kill bacteria that may otherwise be harmful to health, to keep the water comfortable to bathe in and to keep it crystal clear and inviting. To establish the dose rate of chemical you will need for your Above Ground Swimming Pool, you must first know the volume of water to be treated – some typical pool sizes and volumes are listed below.

Common pool sizes and volumes:

12ft diameter x 3ft deep = approximately 2,100 gallons or 9.5m3

12ft diameter x 4ft deep = approximately 2,800 gallons or 12.7m3

15ft diameter x 3ft deep = approximately 3,300 gallons or 15m3

15ft diameter x 4ft deep = approximately 4,400 gallons or 20m3

 To sanitise the water

Test the water daily using our AquaChek test strips and maintain a chlorine level of 2 – 4mg/l (ppm) by adding stabilised chlorine granules alternatively you can use chlorine tablets which can be placed into a floating dispenser. Chlorine granules / tablets produce free active chlorine to kill bacteria and other harmful organisms so that you have the peace of mind of knowing your family’s health is being protected. They contain a built-in stabiliser making them ideal for outdoor pools where chlorine loss to sunlight can be a problem.

pH:

The pH scale indicates how acidic or alkaline the water is,  the lower the pH reading the more acidic the water; the higher the pH reading the more alkaline the water.  To keep the chlorine fully effective and create a comfortable bathing environment, the pH needs to be kept between 7.2 – 7.6.  If the pH rises above 7.6 it can be reduced by adding pH & Alkalinity Reducer.  If the pH falls below 7.2 it can be increased by adding pH Increaser.

Dose rates for adjusting the pH using pH Reducer & Increaser:

Gallons            Cubic Meters    Dose in Grams

2,100                    9.5                         100g

2,800                    12.7                       150g

3,300                    15                           175g

4,400                    20                           225g

The rates shown above are the maximum per application; it may require several doses to correct the pH.

 Green Pools:

 There is always a chance that at some stage during the swimming season, algae will get into your pool and turn the water green. This is likely to happen if the chlorine level is allowed to drop for a few days. If your pool does turn green with algae we advise you to shock dose the pool with a stabiliser-free chlorine such as Fi-Clor Superfast Superchlorinator.

 

NOTE:

Always dissolve granules before adding to pool water.

NEVER MIX CHEMICALS TOGETHER WHEN DISSOLVING.
