20x50 Carbon Spec Sheet

Filtration Media
	ProActive™ 20x50 Carbon

ProActive 20 x 50 Carbonis made from a superior quality anthracite and bituminous, non-viscous coal. This 20 x 50 mesh carbon is the top of the line for chlorine reduction and is recommended for cartridge application or heavy chlorinated water. It is the best carbon we have for removal or reduction of organic contaminates, odor, taste, color, and turbidity.
FEATURES • High adsorption capacity and efficiency. • Super durability that stands up well to backwash. • Low fines, no floats, rinses fast. • Low pH.

Warning For safety and handling purposes, we recommend appropriate protective measures when entering a wet vessel containing granular activated carbon, because wet activated carbon depletes oxygen from air and therefore, dangerously low levels of oxygen may be encountered. In such a case, the oxygen level inside the vessel shall be determined before entering and appropriate protective equipment should be worn when entering, or leave the vessel open until the oxygen level in the vessel is normal.
