CO2 Controller Effective pH control in pool water

The WaterPro CO2 Feeder is designed to utilise Carbon Dioxide (CO2) in the control of pH levels in pools and spas.  

Features

• 0-25 L/Min of air flow using a manually adjustable rotameter
• Switch to set function, on, off, auto
• Pre-wired for remote start/stop from swimming pool controller
• Standard push connectors for 8mm O/D hose
• Quality SMC air solenoid valve 
• IP rated housing
• Quality electrical componentory 

Advantages of CO2

• No handling of corrosive acid containers,
• No corrosion of equipment and facilities from acid fumes,
• No dangerous chemical reactions with chlorine,
• Less danger of excessive low pH in water. Because carbonic acid is a weak acid, the lowest pH value that can be reached is 6.8, even under accidental runaway conditions,

Caution

• CO2 increases the alkalinity of water and is therefore not recommended for applications where high alkalinity is a problem. Total Alkalinity (TA) should be maintained between 80 and 125 ppm.
• High alkalinity increases acid demand, makes it difficult to lower the pH and may result in the formation of bicarbonate scale.
• High alkalinity may be reduced with muriatic acid HCl or dry acid.
