Potassium Nitrate (KNO3) Fertilizer for Aquarium Plants

Potassium Nitrate – KNO3 13.7-0-46

The KNO3 aquarium fertilizer is a Potassium Nitrate solution. The Nitrogen (N) in the potassium nitrate reef tank is essential for chlorophyll production. The Potassium (K) on the other hand is necessary for protein synthesis. Potassium Nitrate for aquariums is therefore required for plants to metabolize Iron (Fe).
