Aquatic life generates a variety of wastes which can rapidly reach toxic levels. Tap water can also introduce undesirable elements. These wastes and bi-products must be removed. Water purification cannot occur without some type of filter material. The proper use of effective and specific media for particular tasks is vital in aquarium filtration. We separate these types into mechanical, biological, adsorptive and chemical filter media
Ehfimech is a coarse mechanical filter material which is to be used as bottom layer filtration. It's hollow ceramic design crates eddies which disperse the water into many paths trapping large debris, whilst creating an even flow of water for subsequent layers of media.
