Seachem 719 Fresh Trace Gal Review

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. Contains only those elements actually demonstrated to be required by fish; 250 milliliters treats 50 gallons for 2 to 4 months.
