As a metallic trace element, it is for aquatic plants only in a so-called chelate compound usable as it is only soluble in water so. The term chelate comes from the Greek word "crab claw". In iron fertilizers are salts often assume the function of the "crab claw". One can easily imagine that, in the "crab claw", the iron in the water is soluble. The water solubility is a prerequisite that the iron can be transported to the green cells of aquatic plants. But, the "crab claw" to the iron again to share, because it can only be so excluded from the plant. The release is usually done by the natural UV content of the aquarium light. Since the dissolved in water and protected by the "crab claws" iron compound enge also flow through the UV sterilizers, these are also irradiated by UV-C light. This additional UV light accelerates the destruction of the "crab claws" and the uncovering of the iron. The effect is similar to the destruction of the DNA of the cell nuclei, only in this case it is an undesirable effect. The iron content of the water drops is usually faster to 0 mg / l as without the use of a UV sterilizer. The problem arises when it comes to lasting iron deficiency and (insert link, Google Search) aquatic plants iron deficiency show. What can be done to prevent the iron deficiency to be expected? The fertilizer industry has recognized the need and particularly UV-stable chelators developed. Our recommendation is to use these specific products with the use of UV sterilizers. The UV-stable manure are not significantly more expensive than conventional water plant fertilizer, so it is worth, here select the right product.
We have put together a short product overview:
Alternatively, you can use any water plant fertilizers, if they change the fertilizer to daily fertilization, for example, as part of daily feedings. Classical water plant fertilizer, with high customer satisfaction, can be found here:
