In a planted tank, the micronutrients added by tap water or fish food might not be sufficient, and the plants’ growth will be less than optimal. Mikro Spezial Flowgrow brings the most important micronutrients of iron, manganese, copper, zinc, boron and molybdenum into the aquarium. This fertilizer is characterised by a less strong nutrient stabilisation, which makes them especially easily available for plants.

Weekly water changes of 25 - 50 % are recommendable in order to prevent micronutrient accumulations in the water.

The basic supply of micronutrients is provided by our waterplant fertilizers Mikro Basic Eisenvolldünger or Mikro Spezial Flowgrow.

The waterplant fertilizer Mikro Spezial Flowgrow adds the micronutrients of iron, manganese, zinc, boron, copper and molybdenum to the aquarium. Especially in a social tank with high numbers of fish all the important micronutrients are supplied in a safe way; nitrates and phosphates are brought into the tank by fish food and droppings. Less well-stocked tanks will have to be supplied with macronutrients via other fertilizers.

The nutrients of Mikro Spezial Flowgrow are stabilised less strongly (by ascorbate, citrate and gluconate) and are thus practially immediately available for the plants. Especially bivalent iron, which is preferred by aquatic plants, is directly brought to them this way. The waterplants will attain lush green colours again, and reddish plants will turn an intensive red.

This less strong stabilisation makes it necessary to add Mikro Spezial Flowgrow daily. It is possible to dose it once a week, however, this results in a less-than-optimal performance.

Kann ich nicht wirklich beurteilen ! Für gutes Pflanzenwachstum sind ja mehrere Bedingungen ausschlaggebend. Derzeitig keine Verbesserungen ....

A good fertilizer, but i bit, in my opinion, too strong and concentrated. I had to change to a drop bottle, so i can easily adjust the dose that i want.
