Natural sea water contains approx. 70 different trace elements. If the salt water aquarium is not sufficiently supplied with trace elements it results in e.g. degenerative growth, pale colors, or a loss of tissue in corals. However, it is not sufficient to change part of the water regularly to rectify such trace mineral deficiencies. For this reason, we developed the NYOS ACTIVE line of trace elements. You will receive professional products which are advanced over a long time and which provide essential trace elements for your corals and invertebrates.
