SEACHEM - Flourish Iron 500ml - Liquid plant iron

Plants can take advantage of iron from Flourish Iron™ much more easily than from EDTA sources because all of the iron in EDTA is in the ferric (Fe+3) state. Since plants require iron in the ferrous state, more physiological energy must be expended to extract ferric iron from EDTA and then convert it to the ferrous state.

DIRECTIONS: Use 1 capful (5 mL) per 200 L of water supplied to maintain approximately 0.1 mg/L of iron. Each flute is approximately 1 mL.
