Cerameco’s DETOX BLOX 6"x6"x2" Block filter media has unmatched biological and mechanical filtering capabilities. Convenient sized 6x6x2 blocks can be placed in large filters or stacked in sumps. Detox Blox is a porous ceramic material that combines surface area and water passing capabilities, making it unmatched for providing biological filtration within a small volume of material. Firing of the ceramic materials at high temperature results in an inert and strong material with impact resistance which will not degrade and become mushy over time as some ceramic foams do. Made in the USA.
We recommend 1 cubic inches of filter media per gallon, ( One 6" x 6" x 2" block for every 70 gallons)
