Tropica Plant Growth Specialised Fertiliser contains all essential nutrients needed including nitrogen and phosphorus. It is suitable for aquariums with lots of plants in comparison to the number of fish, a low number of fish means a lack of nitrogen and phosphorus as fish excrement and food remnants usually provide them. Tropica Specialised Fertiliser is designed in a way that nitrogen and phosphorus in particular are supplied to the plants in the amounts and chemical forms the plants require for optimal absorption and growth.

The waterplant fertilizer has been created for plants which absorb nutrients from the water via the leaves, which typically are the low, compact foreground plants.

Key Features:

  • Contains nitrogen and phosphor for fast-growing and demanding plants
  • Also contains iron, manganese and vital micro nutrients
  • Suitable for aquariums with many and fast-growing plants
  • Absorbed through the plant leaves


Specialised Nutrition is added each week when the water is changed. The pump bottle dispenses 2 mL per push.
We recommend 6 mL (3 pumps) per 50 L water weekly. However, we recommended that this is set in accordance with plant requirements. Specialised Nutrition contains, in addition to micro-nutrients, all essential macro-nutrients. The fertiliser is particularly suitable where plants display a lack of nutrition. However note that if algae growth starts, Specialised Nutrition will promote this growth.

Specialised Nutrition contains nitrogen and phosphorus. Dosage must therefore be adapted to plant absorption rates, to avoid undesirable algae growth. Where signs of algae growth develop, reduce the dosage by 50% and increase water changing frequency by 50%. Changing the water not only reduces the concentration of nutrients in the water, but also removes algae spores, remnants and other accumulated elements from the aquarium water.
