CRYSTAL CAL by Kolar Labs and CALGON CARBON. 300gram carbon in a 32oz jar. As seen in our pictures, creates crystal clear water for all aquarium and pond types with our ultra high quality, sub-bituminous, CRYSTAL CAL CARBON. This is a true liquid phase granular activated carbon, developed to clarify aquarium water specifically for Kolar Labs. Beware of cheap pelletized carbon that is made for air purification and not for water. This is a 4x12 mesh carbon with very low dust, with Reef Aquarium quality, at a very affordable price. For use in reactor, media bag, or canister filter. NOTE: NSF certified material but product is not shipped for human consumption.
