Potassium for aquarium

maintenance, care, compatibility

Sooner or later, there always comes a time when special solutions must be added to the aquarium environment to ensure the vital activity of the aquatic flora. Such additives or fertilizers, designed to feed the aquarium plants, can be purchased as a finished product, and cook yourself.

To ensure the vital activity of plants in the aquatic environment are necessary:

  • macronutrients (potassium, phosphorus, nitrogen);
  • trace elements (manganese, boron, iron, molybdenum, copper, zinc);
  • salts based on magnesium, calcium or bicarbonate.

Manufacturers of fertilizers for aquatic plants offer a fairly wide range of liquid solutions containing both one of the listed elements and a complex of useful substances. For example, the main element of fertilizers such as BIO VERT NANO or AQUAYER Udo Yermolaeva IRON + is iron, and Tetra PlantaPro Macro is a solution containing potassium, nitrogen and phosphorus.

As a rule, such tools are available in the form of ampoules, the contents of which are designed for a certain amount of aquarium water. Another type is branded fertilizers in liquid form, which must be added in exact doses for a certain amount of water.

There are also solid agents, the main representative of which are the tablets of the TetraPlant line. In any case, the procedure for the use of a fertilizer is specified in the attached instructions for use.

But many aquarists independently prepare nutrient fluids for feeding the flora in their aquariums.

72 g of potassium phosphate is stirred in 1 liter of water at room temperature. Everything is well mixed.

Make up the finished solution once – no more than 1 ml per 100 liters of water.

60 g of potassium nitrate (potassium nitrate) stir until completely dissolved in 1 liter of water. Make nitrate solution only once in the same dosage.

110 g of potassium salt (potassium sulfate, or potassium sulfate) dissolve in 1 liter of water with a temperature of +25 degrees. Per 100 liters of water in the aquarium should make 10 ml of solution.

You can prepare a complex fertilizer using a larger number of elements. Preparation Procedure:

  • boil 700 ml of water (distilled), let cool slightly and dissolve in it 10 g of magnesium sulfate, citric acid – 30 g, ferrous sulfate – 10 g, copper sulfate – 0.5 g, 0.6 g of zinc sulfate;
  • let the solution stand for 1 hour;
  • Add and dissolve 0.3 g of boric acid, 9 g of potassium sulfate, 4 ampoules of citovite, 4 ampoules of ferovite, 2 ampoules of vitamin B12 and 20 ml of sulfuric acid.

Attention! It is necessary to observe safety measures when handling sulfuric acid!

  • then it is necessary to add distilled water to the solution, bringing the volume to 1 liter.

Complex fertilizer is ready. It can be applied daily at the rate of 1 ml of fertilizer per 50 l of water in the aquarium.

In water, plants need oxygen and carbon dioxide. They also need nitrogen, which they use to make protein.

Mineral substances such as phosphorus and trace elements such as silicon, magnesium, iron, etc. are less needed.

If the plants lack potassium, then they will slow down photosynthesis, there will be a shortage of proteins. In this case, they lose the color of the leaves, lose them.

Since the potassium is quickly disappearing from the water, you need to constantly take care of its quantity in the aquarium when doing your own feeding. It is possible to judge what fertilizers representatives of aquatic flora are lacking by the state of their leaflets. If there is a shortage of top dressing, in which there is iron, or other trace elements, the leaves begin to be covered with bright spots and stop growing, the seedlings may lose some of their stems.

With a prolonged shortage of food, they may simply die.

If plants have a strong root system, then fertilizer should be placed in the ground. Sold special tablets that contain iron, potassium and other trace elements.

You should buy fertilizers for aquatic species, otherwise it will be difficult to properly feed.

Special tablets for feeding water greens contain the right amount of iron and other trace elements. They need to be properly placed in the soil so that the nutrients are evenly distributed in the water and the soil. Solid fertilizers should be buried in the ground to the desired depth with your own hands, according to the instructions.

This will ensure proper nutrition to the roots.

There are also liquid preparations that also contain iron, potassium, nitrogen, phosphorus and other elements necessary for the development of seedlings. They are added directly to the water. They are intended for species that freely swim in the water.

They are easier to use, as the control over the amount of nutrients can be controlled. To do this, you can simply change the water to the fish.

Applying a liquid feed should be done regularly, it will also provide control over the amount of nutrients in the water.
