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.
Mechanical filter media work much like a sieve trapping particulate waste as it passes through the material.
A completely neutral filter wool. The fine phenol free structure of this synthetic material traps tiny particles of dirt. It should be loosely placed as the last layer in your filter arrangement. For models 2222, 2224, 2226, 2228 we recommend a special EHFISYNTH pad.
