Nitrogen is one of the essential nutrients required for the growth and reproduction of plants, as it is one of the main components of chlorophyll. Chlorophyll is an integral part of plants that uses light, water, and carbon dioxide to produce the sugars needed by the plant, and this process is called photosynthesis.

The appropriate level of nitrogen in planted aquariums is, on average (depending on the type of plants), up to 30 milligrams per liter. If the nitrogen level in the aquarium falls below the plants’ needs, their growth will significantly decrease, as it is one of the main limiting factors for plant growth. Symptoms of nitrogen deficiency include reduced growth rate, yellowing of leaves, and stunted growth. Typically, symptoms of deficiency appear first in older leaves rather than younger ones, as nitrogen can be transferred from older parts to younger parts of the leaves. Additionally, severe nitrogen deficiency can lead to leaf drop. On the other hand, high levels of nitrogen can make plants brittle and increase the growth of unwanted algae in the aquarium.

Deep Ocean Nitrogen Fertilizer can easily and safely increase the nitrogen concentration in plants with quick absorption and completely eliminate the symptoms of nitrogen deficiency.

Basic Usage Instructions:

Shake the bottle well before use, then add half a cap (2.5 cc) for every 160 liters of aquarium water twice a week or as needed based on symptoms of nitrogen deficiency, such as stunted growth or chlorosis (pale coloration of the plants).

Professional Usage Instructions:

Before use, measure the nitrate level of the aquarium water using the Deep Ocean nitrate test kit.

Reference 1: Each cc of Deep Ocean nitrogen fertilizer can increase nitrate concentration by 6.7 ppm in 10 liters.

Reference 2: 5 cc of Deep Ocean nitrogen fertilizer can increase nitrate concentration by 1.7 ppm in 200 liters.

Note: Maintaining a relative ratio of 10 parts nitrogen for every 1 part phosphorus leads to stable plant growth without encouraging excessive algae growth, as an imbalance between phosphate and nitrate can cause unwanted algae.

Attention: The provided usage instructions and weekly fertilization schedule represent a general method and average consumption for all planted aquariums. The volume and needs of plants, as well as the type of aquatic organisms in each aquarium, may vary. Therefore, to achieve the best condition for plants, the amount of fertilization should be tailored to the volume and needs of the planted species in the aquarium. The aquarium manager should adjust the fertilizer dosage up or down based on the growth status, color of the plants, and their visual symptoms. It is evident that excessive fertilization can lead to algae growth, while insufficient fertilization can result in reduced color and growth.

Explanation: Given the very high quality of Deep Ocean nitrogen fertilizer and the necessary stability in the production process, it is possible to use a smart calculator to accurately calculate the amount needed for maximum efficiency in the aquarium. Thus, the closer the entered volume of aquarium water is to reality, the more accurate the final consumption amount will be.

Note: The amount calculated in this calculator is defined based on nitrate concentration. To convert this amount to nitrogen, you can use the Deep Ocean application.
