HTH Dry Chlorine

Carbon dioxide gas became very popular in the UK and Europe during the late 1980's for correcting pH.

It is undoubtedly one of the major steps forward in the chemical treatment of pool water though it is not always cost-effective to use in high alkaline waters

PURPOSE
>	pH reducer

FEATURES
>	Available in cylinders or bulk storage
>	Safer to use than other chemicals
>	Difficult to mix with other chemicals and form chlorine gas
>	Clean to use without handling if bulk system is used

DOSING
>	Cylinder is under pressure. A solenoid linked to automatic controller is activated when pH rises above set point.
>	CO2 is a much kinder product to use than hydrochloric acid or sodium bisulphate, eliminating the chlorides and sulphates that these products bring to the pool. CO₂ in fact adds little in the way of TDS to the pool so increases bather comfort. It works best in areas of the country where the mains water alkalinity is less than 150 mg/l.
>	Product can be purchased in various sized cylinders or be transferred by tanker to bulk storage
