AQUATIC PLANTS FERTILIZATION: Why and How fertilize planted Aquarium

Immagsfdgdsgine_2 copiaAquatic plants for living and growing in a biosystem (the aquarium) must to realize chlorophylline photosynthesis and with the essential elements such as water, proper illumination and the right amount of Carbon Dioxide (CO2) dissolved, the necessary quantities of nutrients, also called fertilizers, will be essential. If all those elements are correct,will originate the so-called “Nitrogen Cycle”, which will allow a good development of plants and animal living inside the tank. In this article we will see what, and how many nutrients are needed for plants growth, but first it is crucial to know that, unlike terrestrial ones, they can absorb nutrients through the roots and through the stem and the leaves. Most aquatic plants live well only if both ways of nutrition are active and well balanced, so you will have to consider to use liquid fertilizers that are soluble in water and bottom substrate fertilizers:

macroplus_homeLIQUID FERTILIZER: Liquid products generally have all nutrients required for any plants, should be administered daily or weekly and can be generally subdivided into “macronutrients”, “micronutrients” and trace elements. The macronutrients, are usually nitrogen (N), phosphorus (P), sulfur (S), calcium (Ca), magnesium (Mg), potassium (K) are indispensable elements, in right quantities, for the growth of any plant. The micronutrients are iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo), cobalt (Co), boron (B) and are required in small quantities to produce new organic matter. These are generally used for red colored plants. The quantity to be administered are always indicated on the packs and are based on the volume of tank water and the amount of plants, there are various concentrations and with many different elements, precisely to suit the different needs of the various plants, so it is advisable to know the type of absorption of the plants in the aquarium and consequently buy the appropriate fertilizers.

ImmdfasagineSUBSTRATE FERTILIZER, BOTTOM DRY POWDER: The bottom of the aquarium represents the substrate in which plants grow and produce roots, so it must contain all nutrients such as (Fe, Bo, Mn, Cu, Zn, Mo) necessary for their metabolism in the right proportions. Some of these elements can also be absorbed by water, but are generally more available and less polluting if present in the bottom where they are unavailable for algae that compete with plants. In addition, the substrate has the ability to exchange cations (CSC), that is mean it is capable of absorbing all the essential nutrients to subsequently give them slowly to the plants. Remember that the common inert cosmetic sand or gravel, are characterized by insufficient CSC, and can also create anaerobic areas were can repruduce the harmful bacteria. Ultimately, the bottom is an indispensable “accumulator” of nutrients and needs to be carefully plan. When you are making an aquarium set up, we suggest to prepare, in the following, way two or three successive layers for create optimal conditions for roots:

We will help the perfect development of the “nitrogen cycle”.

ImmagisdAne2nd LAYER: for the second layer you will need to place the so-called dry fertilizers or powder fertilizers soil for substrate, we find them on the market and are composed by: laterite rich in iron and aluminum, stick tablet fertilizer, fertilizer in various kinds of powder, allophone bottoms, fertilized soil. All of which contain substances such as Fe, Bo, Mn, Cu, Zn, Mo, with slow release, and can often stabilize PH.

dsfdsfd copia3rd LAYER: This is the last layer that you you will pose and is usually made of sand or gravel of various diameters of siliceous origin, or quartz. It will be necessary to separate the bottom environment from the water, avoiding too much fertilizer release and “pollution” with the “work” of fishes, is often also used as an aesthetic chromatic factor. For well-planted aquariums, we recommend the use of fertilized soil that will not cede the substances in water keeping it crystalline, will be very useful for plants growth and PH control. If you have an aquarium already set up and started, we suggest to siphoning it carefully to eliminate the excess of organic waste present (foods and escrements that contain excessive amounts of nitrogen and phosphorus), and then add balls or tablet of fertilizer sticks under the substrate, put those at identical distances to cover all the bottom of the tank. Only then plants will have the right amount of elements to absorb through the roots.

All-About-Aquariums3In conclusion, liquid fertilization and substrate fertilization, for a planted aquarium, are fundamental for two important reasons: fertilizing means nourishing plants and accelerating metabolism, this improving the proper development of the nitrogen cycle and increasing the well-being of all other living things In the aquarium. Another reason to fertilize, is to fight and avoid the formation of algae that are in competition to get the nutrition present in the water, however, you must to provide the right quantity and the right kind, otherwise everything that will remain in suspension will be vital for algae. You must also be careful to the tap water if you are planning to use it, because it usually contains abundant amounts of different ions (often unknown). You should therefore test it, eventually dilute with osmosis water and add missing nutrients, otherwise you will see the plants lose color and change from green to yellow, or you will notice loss of leaf tissue. Another advice to nourish the plants and at the same time to keep the water free of suspended excess elements is to put activated charcoal active carbon (pellet) in the filter, which will remove unused plants nutrients and avoiding formation of algae.
