Seachem Flourish Trace 500 ml (17 floz.).

Flourish Trace supplies a broad range of trace elements demonstrated to be necessary for proper plant health and growth (see right panel 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.

DIRECTIONS:

Use 1 capful (5 mL) for every 80 L (20 gallons*) twice a week.
