Seachem Flourish Iron 500ml

Seachem Flourish Iron provides iron in the ferrous (Fe2+) form, which is the most readily absorbed by aquatic plants. With a concentration of 10,000 mg/L, it is one of the most potent iron supplements available for hobbyist use. Iron is critical for chlorophyll synthesis, and deficiency presents as yellowing of new leaves (interveinal chlorosis). Dose 1ml per 200L, two to three times per week or as needed. Works synergistically with other Flourish supplements and CO2 injection for maximum plant health.
