Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplementit should be used in those case where the iron requirements exceed that which can be delivered. Flourish at the recommended dose or signs of iron deficiency appear (such as short and slender stems or yellowing between veins).
Plants are able to much more easily derive a benefits from Flourish Iron than from EDTA-Iron source because all EDTA iron is in the ferric state. Since plants require iron in the ferrous state,additional physiological energy must be expended in order to extract the ferric iron from EDTA0ion and then convert it to be the ferrous formcontains no phosphate or nitrate. Flourish Iron is safe for invertebrates such as shrimp
Use 1 capful( 5 mL) for each 200L (50 gallons) or as required to maintain about 010 mg/L iron. For smaller doses please note that each cap thread is about 1 mL,use multitest iron test kit to monitor iron concentrations. Due to rapid utilization,test within 30 mins. Use as needed to combat signs of iron deficiency(usually seen in new growth)which includechlorosis(yellowing) of tissue between veins and. short and slendr stems
