NOPO Control
Freshwater / Water Care / NO3 & PO4 Control

All advantages

  • Reduces even high PO4 & NO3 values
  • Usable in every saltwater & freshwater aquarium
  • Easy and safe to use


NOPO Control is a specially developed solution of select hydrocarbons for the safe and optimal biological degradation of nitrate (NO3) and phosphate (PO4) in every saltwater and freshwater aquarium.

NOPO Control maximises the performance of the bacteria present in the aquarium, enabling an efficient degradation of nitrate and phosphate even when nutrient levels are high.

NOPO Control improves the overall biology on a long-term basis and serves as an extra energy source for your corals – for maximum growth and sumptuous colours.



• For maximum effectiveness, we recommend using NO3PO4 Control together with Special Blend. Maintain an interval of at least 48 hours between the dosages of both products.

• Check the NO3 & PO4 levels regularly in your aquarium to avoid a limitation of them.

• Make sure your PO4 level does not drop to 0, as it is a vital energy source needed by corals, plants and bacteria and is indispensable for successful nitrate degradation.

• If a bacterial bloom occurs, we recommend using a UV-C clarifier.


Start with a daily dose of 2 ml per 100 litres of water and increase this to a maximum of 10 ml per 100 litres of water if needed, until a reduction in the nutrient levels can be measured.

Maintain the selected dosage until reaching the desired nutrition levels and then adjust this if need be so as to keep the levels stable.
