The chemical quantities are approximate. Use them as a guide until you have established the
correct amount for your pool.
To establish the size of your pool
Apply the following calculation. This will give you a reasonably accurate indication.
Measure in Meters/
Length x Width x Depth x 1000 = Volume in litres i.e. 10m x 5m x 1.5m x 1000 = 75000 ltrs
To convert to gallons multiply by 0.22. I.e. 750000 x 0.22 = 16500 Gals
pH CORRECTION
Correct Reading 7.0 to 7.4
High Reading Use Dry Acid (Sodium Bisulphate) to reduce pH Reading
