Seachem Discus Trace Freshwater Supplement 250 mL

Seachem Discus Trace supplies a broad range of trace elements demonstrated to be necessary for proper fish health and growth. Unlike terrestrial animals, fish obtain nutrients from both their food and environment. Essential trace elements are normally depleted through biological utilization, oxidation, and precipitation, making regular restoration important. Discus Trace contains only those elements demonstrated to be required by fish, including calcium, magnesium, iodine, potassium, copper, iron, and zinc. One 250 mL bottle treats 200 liters (50 US gallons) for two to four months.
