EHEIM FILTER WET/DRY 2227-37
As an external filter the EHEIM Professionel wet/dry filter is the first filter to offer the perfect technology of a "breathing" alternating contact with the filter medium. The bacteria colonies are rhythmically flushed and aerated. This creates ideal conditions for considerably accelerated decomposition of almost all solved pollutants. Ammonia is decomposed 2/3 faster and nitrite 1/3 faster than conventional canister filters. Only filtered oxygen rich water is returned to the tank. Eheim wet/dry filters come loaded with ehfisubstrat pro and are biological filters only.
