Optimum PoolSan performance is between pH of 6.8 and 7.4
Verify the volume of water in your pool
Correct pH control of pool water is essential to maintain ideal bathing
conditions.
If pH is too high, the water will be less comfortable for bathers, sanitizers
lose their efficiency and the water may become dull and cloudy.
Ideal bathing conditions exist between a pH level of 6.8 and 7.4 with total alkalinity of 80-150 mg/l (ppm).
Determine the pH level of your pool by using a pH test kit. Then if necessary adjust the pH following the instructions below.
TO DECREASE pH
Add 120g of PoolSan pH- per 10,000 litres of water (If you know your
pool water volume in imperial gallons, multiply the amount of gallons
by 4.5 to give you an estimate of the volume in litres. E.g. 1,000 gallons
is approximately 4,500 litres. 1000 litres is the metric equivalent of
220 imperial gallons).
Apply the required amount of PoolSan pH - by pre-dissolving the product
in a clean container with clean, warm water. Pour the solution all around
the pool parameter and keep the pump running to allow re-circulation.
Wait for a minimum of 2 hours then recheck pH level. If it is still above
7.4 then repeat the above procedure.
Allow a minimum of 1 hour after application of this product before swimming.
TO INCREASE pH
Add 120g of PoolSan pH+ per 10,000 litres of water (If you know your pool water volume in gallons, multiply the amount of gallons by 4.5 to give you an estimate of the volume in litres. E.g. 1,000 gallons is approximately 4,500 litres. 1000 litres is the metric equivalent of 220 imperial gallons).
Apply the required amount of PoolSan pH+ by pre-dissolving the product in a clean container with clean, warm water. Pour the solution all around the pool parameter and keep the pump running to allow re-circulation. Wait 1 to 2 hrs then re check the pH level. If it is still below 6.8 then repeat the above procedure.
