DUO Add-On N supplements our DUO basic supply with a nitrogen source. This can effectively counteract a nutrient deficiency.


Due to the coupling to the basic supply, regular dosing takes place, thus achieving constant nitrogen availability.


In our analyzes we often find a lack of nutrients, which can lead to problems in coral maintenance and the unwanted growth of cyanobacteria or dinoflagellates.
To respond to this situation, we have developed the Oceamo DUO add-ons nitrogen and phosphorus. The add-ons are packed in a practical dosing syringe and are mixed with the DUO supply solutions according to the instructions. 


Typical dosage: 2 ml DUO Add-On N per liter DUO Approx.


For mixing into DUO Approx. Do not use undiluted.
