The element™ Z Reactor is designed to utilize zeolite as a filter media in removing various pollutants from a reef aquarium while also providing a media to house beneficial bacteria. This method of filtration has been shown to increase coral coloration in many cases by reducing organic nutrient loads in reef aquaria to much lower levels. An important factor in use of the element™ Z Reactor is to utilize the wash feature of the reactor on the media 1-2 times per day. The wash of the media allows for more efficient filtration by keeping the bio film that grows on the media at a minimum while also feeding reef aquarium inhabitants the bio film itself.
