The Tropica Premium Nutrition aquatic plant fertilizer without nitrogen and phosphorus is best suited for an aquarium with many fish and relatively slow-growing aquarium plants. The Tropica PLANT CARE Premium Nutrition contains iron, manganese and important micronutrients, which are usually insufficient in an aquarium with many fish. Not available in Tropica Premium Nutrition, however, is nitrogen and phosphorus... these substances are usually already sufficient by the feeding and excretions of fish in the aquarium available.
With the practical dosing pump on the Tropica Premium Nutrition bottle, the desired amount of liquid water plant fertilizer can be dosed quickly and easily. The dosages recommended by Tropica ensure good plant growth in your aquarium.
The Tropica Premium Nutrition Fertilizer should be added every week in conjunction with the water change, with Tropica recommending a dosage of 6 ml (3 times) to 50 liters of water, but advising that the aquatic plants in the aquarium should be considered - yellowish leaves at the plants are usually a sign of nutrient deficiency, for example.
It is recommended that minimum 25% of the aquarium water is changed every second week. If undesirable algae growth does occur, then we recommend increasing water change frequency (up to 50%) and planting additional rapid growth waterplants such as Hygrophila, Vallisneria and Egeria.
