Alkalinity Increaser

It is necessary to keep the alkalinity level of swimming pool water within the range 0f 100 to 150 mg/l. or parts per million, to prevent erratic swings in the pH value as pollution and other chemicals are added to it.

Sodium Bicarbonate is added to water to raise its alkalinity level. When the alkalinity level is kept in the range of 100 to 150 mg/litre, it makes water treatment more effective and helps to prevent damage to pool equipment too.

Dose this by adding a measured quantity to a bucket that is three-quarters full of water - warm water works better - and stir to help it to dissolve. Pour off the liquid into the pool by the inlet, with the pump running, and maybe add more water to mix the solids until suspended in solution. Allow 12 to 24 hours for effective distribution (depends on flow rates and pool volume), and then test the water before dosing again.
