Cerameco’s DETOX BLOX 1" Cubes filter media have unmatched biological and mechanical filtering capabilities. Convenient sized cubes can be placed in filters and 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. Fusing 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 foam materials do. Made in the USA.
For maximum performance use 1 lbs of block for every 25 gallons of water.
