Seachem Discus Trace Elements Supplement 16.9 fl. oz

Discus Trace supplies a broad range of trace elements demonstrated* to be necessary for proper ‹ªsh health and growth. Unlike terrestrial animals, fish obtain nutrients from both their food and environment. Trace elements are normally depleted by utilization, oxidation and precipitation, thus it is important to restore them on a regular basis. Discus Trace contains only those elements actually demonstrated* to be required by fish.
