## Description

Product description               Fast-Acting & EffectiveCrystal Cal Activated Carbon was painstakingly sourced by our partners at Calgon Carbon and is made specifically for aquarium water filtration. It features a sub-bituminous coal base with optimum pore structure to help remove colors, tannins, odors, medications and other common contaminants from aquariums and ponds.Crystal Cal’s unique fabrication process results in an activated carbon that combines the best of lignite and coal-based carbons for superior removal and mechanical stability. Crystal Cal has a large pore structure, similar to that of lignite carbons, for effective removal of higher molar weight color inducing molecules from aquariums. This effective pore structure is combined with dramatically improved mechanical stability of coal-based granules to resist physical breakdown and dust production results in an ideal product for aquarium use.Most of the carbon sold for fish tanks is made to treat air, resulting in high levels of contaminants, such as phosphates, which may leach into water. All of our activated carbon is produced to rigorous food and drinking water standards for unparalleled consistency and quality that minimizes harmful trace contaminants. We are proud to say that Crystal Cal has low levels of extractables and dust and is washed and steam activated to higher standards of “Liquid Phase Carbon.”Get to Know Kolar LabsKolar Labs has been the source for premium filter medias in the aquarium industry for years.
