Seachem Flourish Trace

Flourish Trace supplies a broad range of trace elements demonstrated to be necessary for proper plant health and growth (see below for signs of deficiencies). Trace elements are normally depleted by utilization, oxidation and precipitation. The latter two processes occur more rapidly than with other micronutrients. This makes it important to restore trace elements on a regular basis. Flourish Trace may be used alone or in conjunction with Flourish. Best results are obtained when both are used. Flourish Trace is safe for invertebrates such as shrimp.
Signs of Trace Element Deficiencies

Boron: Death of stem and root apical meristem, leaves twisted, young tissue most affected
Cobalt: used for nitrogen fixation, same as nitrogen deficiency signs (stunted growth)
Copper: Young leaves dark green, twisted, wilted, tip remains alive
Manganese: Chlorosis of young leaves, with smallest veins remaining green, necrosis between veins
Molybdenum: Chlorosis, twisting, death of young leaves
Zinc: Reduced leaf size, shortened internodes, chlorosis, spotted leaves, older leaves most affected<
Nickel: lack of germination or seed formation, required for iron absorption

Directions

Use 1 capful (5mL) for every 80 L (20 US gallons) twice a week. When using in conjunction with Flourish, dose on alternate days.
