Reef Nutrients Calculator

Calculate nutrient input from fish food to estimate nitrate and phosphate levels in your reef aquarium

Our advanced reef nutrients calculator helps you understand how feeding affects your aquarium's water chemistry. By analyzing the protein and phosphorus content of fish food, you can estimate the resulting nitrate and phosphate levels in your tank. This tool is essential for maintaining balanced reef nutrition and preventing nutrient-related issues like algae blooms or coral bleaching.

Measurement Units
Total Mass (grams)

Enter the total mass of the food in grams.

Protein %

Enter the protein percentage of the food.

Phosphorus %

Enter the phosphorus percentage of the food.

Water Volume

Enter the total water volume of your aquarium.

Nutrient Levels

The calculated nutrient levels rise in your aquarium.

0
ppm
NO₃ (Nitrate)
0
ppm
PO₄ (Phosphate)
Note: These calculations estimate nutrient input from food. Actual tank levels depend on biological filtration, coral uptake, and other factors.

Optimize feeding schedules and portion sizes to maintain ideal nutrient levels for healthy coral growth and vibrant fish colors.

Enter your daily feeding amount, food composition details, and tank volume. Our calculator will estimate the daily nutrient input and resulting water parameter changes.

Perfect Nutrient Balance

Maintain optimal nitrate and phosphate levels for vibrant coral colors and healthy growth.

Algae Prevention

Prevent nuisance algae blooms by controlling nutrient input from feeding schedules.
