Iron (Fe) is an important component of plant nutrition. In case the plants have fading leaves this may be due to lacking iron.
The sera Fe-Test provides quick information about possible deficiencies. Directed fertilization with sera florena or sera florenette immediately counteracts the deficiency. Detection of chelatized (stabilized) iron is possible.
Iron (Fe) is important for the formation of leaf green (chlorophyll). If there is a lack of iron, the plants will show significant so-called iron chlorosis with a bright, pale leaf color and leaf veins staying visibly green, which is best seen in new growths. Iron is ideally added to a planted aquarium with an complete iron fertilizer. Together with other important trace elements such as manganese, boron and zinc, but also with nutrients such as potassium, the need for micro-nutrients and, at least in some parts, for macro=-nutrients is covered. The Fe content can be determined using Sera FE water test. This is partly due to the nutrient stabilization of the respective liquid fertilizer.
If there is too little or too much iron in the aquarium water can be seen with the naked eye, though. A lack of iron leads to the symptoms mentioned above. An overdose often intensifies the growth of red algae, (black beard or staghorn algae). The Sera FE test kit should therefore definitely be part of the basic equipment for any less-experienced planted tank keeper or as a security reference for advanced aqua-scapers.
In many reef tanks, the only supplements added are calcium and a source of alkalinity (and all of the chemical impurities that come along with these additives and, of course, food). No others, it would seem, are mandatory for keeping many organisms. There is one other supplement, however, that has proven itself to be very useful in many reef tanks: iron. Specifically, it has proven itself to be useful in applications involving tanks with substantial growths of macroalgae.
The benefit of iron appears to be at least two-fold (and maybe three-fold). The main benefit is that at least some species of macroalgae grow faster, and appear a darker, more attractive green, when the tank is dosed with iron. In addition to the aesthetic benefits, this increased growth permits the macroalgae to be a better nutrient export system. A secondary benefit is that faster growing macroalgae may better compete with microalgae, which is often a source of frustration to reefkeepers. One more speculative benefit is that it may decrease the likelihood of caulerpa undergoing sexual reproduction, creating water quality problems.
