Dosage incl. dosage calculator

Your aquarium
(net volume of water in litres)

10 ml per 100 L of water

Add 10 ml per 100 litres of water to increase the phosphate content by circa 0.1 mg/L.

The optimum phosphate content is 0.1-1 mg/L.

FAQ Questions and answers

A phosphate deficiency is shown by very slow plant growth, reduced shoot tips and discoloration of the plant leaves. The otherwise bright green usually turns very dark to violet. A phosphate deficiency can be identified particularly well in stem plants, as they usually grow very quickly.

The optimal phosphate content in a freshwater aquarium is 0.1 – 0.25 mg/L. To increase the PO4 value, use our phosphate fertilizer Plants P. This is nitrate-free, prevents a phosphate deficiency in the long term and supports metabolic processes.

The ideal phosphate value is:
• Saltwater = 0,03-0,1 mg/l
• Freshwater = 0,1–1 mg/l

Note that bacteria absolutely need a certain amount of phosphate as an energy source in order to carry out important biological processes (such as denitrification NO3 nitrate -> N2 nitrogen) in the aquarium. Since NO3PO4 Control increases the growth and performance of the bacteria in the aquarium, the phosphate requirement naturally also increases. Therefore, measure the phosphate level regularly (at least once a day).

Basic P is a stable and specially tailored phosphate mixture for a targeted increase in the PO4 value in any saltwater aquarium. Basic P effectively prevents a phosphate limitation that is dangerous for corals and sustainably increases their growth and health. Dose 10ml per 100L of water to increase PO4 by 0.1mg/L.

Plants P is a specially developed phosphate fertilizer for all types of aquatic plants in freshwater aquariums. Plants P supports magnificent plant growth and sustainably prevents a phosphate deficiency in your aquatic plants. Add 10 ml to 100 liters of water added to increase the phosphate content by approximately 0.1 mg/L.

Tips & Tricks
  • For maximum plant growth, use Plants P in combination with our range of fertilisers.
  • A greater density of plants prevents the emergence of algae in a natural manner.
  • If phosphate levels are too low, the growth of the aquatic plants can stagnate.
