Iron Chelate Fe DTPA 7% - Dry Aquarium Fertilizers - 100g
Iron ( Fe) an essential micronutrient for aquarium plants
Optimal levels of iron ( Fe ) : 0.2-1ppm. It's can be determined with a suitable water test. Iron is an essential micronutrient needed by all plants.
Deficiency of iron ( Fe) : Causes less chlorophyll formation in plant's new shoots. It can easily be identified if new leaves are pale in coloration. Iron deficiency can be seen first on fast growing plants . Iron deficiency can easily be corrected by adding iron fertilizer. Aquatic Plants absorb iron very quickly. After a few hours, iron might not be determinable anymore
The best iron fertilizers are the chelate iron fertilizers. Chelates are the compounds that stabilize metal ions ( in this case - iron ) and protect them from oxidation and precipitation. Different chelates ( EDTA, DTPA, EDDHA) hold iron ions in different strengths at different pH levels. They also defer in their susceptibility to iron replacement by competitive ions. For example, at high concentrations, calcium or magnesium ions may replace the chelated metal ion. These chelated fertilizers also ensures that the iron is kept in ferrous state, plants absorb iron in ferrous state. DTPA iron chelate is effective up to pH levels of 7.5. This chelate has less affinity to calcium compared to EDTA chelate
To make your solution, mix 71g of iron chelate Fe DTPA 7% to 500ml water ( Preferably RO water ). We suggest using Ro water because most tap water has traces of phosphate which reacts with the iron.
Add 5mL of above solution per 100litres of tank volume to reach a target of 0.5 ppm. We suggest dosing daily at 5ml of your mixed solution per 100 litres of tank volume if it is high light planted aquarium otherwise reduce the dosing accordingly
