Iron was one of the very first fertilizers that was commercially made for aquarium plants! It explains how much important iron is for aquarium plants! The frequency of iron deficiency in aquarium plants is higher than any other nutrient deficiencies. Among all the micronutrients, iron is the one that is most used. Some hobbyists also take it as a macro nutrient.
=>Chlorophyll production decreases when there is a lack of iron. The younger leaves are affected first. The shoot tips of the leaves first get a reddish purple stain and then gradually turns to white.
=>In some plants, the leaves grow smaller, i.e. Egeria Densa.
=>light colored spots or stripes may appear on the leaves of Echinodorous species plants.
=>The leaf tissue turns yellow or white faster than the veins, which remains greenish.
=>A strong iron deficiency may result in necroses on the new leaves. Necroses are black holes and spots on leaves.
=>Faster growing plants show iron deficiency symptoms first.
=>If the situation gets worse, the plants may die for having no chlorophyll at all.
EDTA vs DTPA vs EDDHA Iron.
Fe-EDTA which is commonly available in Bunnings/Garden shops etc is very "easy" and rapid for plant uptake, but the trade off is that it does not last long in the water column solution.. this iron chelate is stable at pH below 6.0. Above pH of 6.5, nearly 50% of the iron is unavailable,therefore this chelate is ineffective in alkaline environment.This chelate also has high affinity to calcium, so it is advised not to use it in calcium-rich soils or water.
Fe-DTPA ( LCA Product ) - It takes a bit more energy, but last several days, so the Fe is available to the plant longer, this iron chelate is stable in pH levels of up to 7.5, and is not as susceptible to iron replacement by calcium.
Fe-EDDHA - this chelate is stable at pH levels as high as 11.0, but it is also the most expensive iron chelate available.
