Redfield Ratio Calculator

The Redfield Ratio, developed by Alfred C. Redfield, represents the molar ratio of carbon (C), nitrogen (N), and phosphorus (P) in marine phytoplankton. It is approximately 106:16:1 for C:N:P. This ratio is crucial in understanding nutrient limitations in aquatic ecosystems. Monitoring and adjusting nutrient levels in reef tanks should aim to approximate this ratio to support a healthy coral reef ecosystem.

FAQs


How do you calculate Redfield ratio?
The Redfield ratio is calculated by comparing the molar ratio of carbon (C), nitrogen (N), and phosphorus (P) in a given sample of organic matter, typically in aquatic ecosystems. The formula for the Redfield ratio is:

Redfield Ratio = C:N:P

What is the Redfield ratio? The Redfield ratio is a stoichiometric ratio that was developed by Alfred C. Redfield in the 1930s. It represents the typical molar ratio of carbon, nitrogen, and phosphorus found in marine phytoplankton and is used to understand nutrient limitations in aquatic ecosystems.

What is the Redfield ratio for reef tanks? The Redfield ratio for reef tanks can vary depending on the specific needs of the corals and other organisms in the tank. It’s important to monitor water parameters and adjust nutrient levels as needed to support a healthy reef ecosystem. Ratios similar to the natural Redfield ratio (approximately 106:16:1 for C:N:P) can serve as a guideline, but adjustments may be necessary.

What is the ratio of Redfield to mass? The Redfield ratio is not typically expressed in terms of mass; it is a molar ratio. It represents the relative proportions of carbon, nitrogen, and phosphorus in terms of moles, not mass.

What was the Redfield ratio in 1934? The Redfield ratio, as formulated by Alfred C. Redfield, was not specifically defined as a single value in 1934. Instead, Redfield’s work laid the foundation for understanding nutrient stoichiometry in marine phytoplankton, which later led to the concept of the Redfield ratio as approximately 106:16:1 for C:N:P.

What is the formula for ratio? The formula for calculating a ratio between two quantities is: Ratio = (Quantity A) / (Quantity B)

What is the Redfield ratio of 1963? The Redfield ratio itself did not change in 1963; it remained approximately 106:16:1 for C:N:P, as originally proposed by Alfred C. Redfield. However, research and understanding of nutrient ratios in marine ecosystems may have advanced during that time.

What is Redfield ratio 1958? The Redfield ratio in 1958 would still have been approximately 106:16:1 for C:N:P, as this ratio was proposed by Alfred C. Redfield and was widely accepted in the field of oceanography.

What is the Redfield ratio quizlet? A “Redfield ratio” on Quizlet could refer to flashcards or study materials related to the Redfield ratio, which is a concept in the field of marine biology and ecology. It’s used to describe the molar ratio of carbon, nitrogen, and phosphorus in aquatic ecosystems.

What is the best flow pattern for a reef tank? The best flow pattern for a reef tank depends on the specific needs of the corals and organisms in the tank. Generally, a combination of turbulent and laminar flow patterns is recommended to ensure proper oxygenation and nutrient distribution. It’s important to mimic natural water movement patterns found in coral reef environments.

What is the best flow rate for a reef tank? The ideal flow rate for a reef tank depends on the tank size, coral types, and equipment used. It typically ranges from 10 to 30 times the tank’s volume per hour (e.g., for a 100-gallon tank, a flow rate of 1000 to 3000 gallons per hour is often recommended). However, it’s essential to monitor the corals’ response and make adjustments as needed.

What is the ideal tank ratio? The ideal tank ratio is a vague term and can refer to various aspects of a fish tank, such as the ratio of fish to tank size, fish to water volume, or the ratio of species in a community tank. The specific ideal ratios will depend on the type of fish, tank size, water parameters, and the goals of the aquarium.

What is the Redfield ratio in freshwater? The Redfield ratio is a concept primarily applied to marine ecosystems. In freshwater ecosystems, the stoichiometric ratios of carbon, nitrogen, and phosphorus can vary widely depending on the specific environment and the types of organisms present. The Redfield ratio is not typically used to describe freshwater ecosystems.

What is the ratio of mass of a substance? The ratio of the mass of a substance refers to the comparison of the mass of one substance to the mass of another substance, typically expressed as a fraction or decimal. It is used to describe the proportion of one substance relative to another.

What is an example of a ratio ratio? A “ratio ratio” is not a common term. Ratios typically compare two quantities or values. For example, the ratio of apples to oranges in a fruit basket could be expressed as 2:3, indicating that there are two apples for every three oranges.

What are 3 ways to find a ratio? Three common ways to find a ratio between two quantities are:

  1. Direct Comparison: Compare the quantities directly to determine the ratio. For example, if you have 5 red marbles and 3 blue marbles, the ratio is 5:3.
  2. Fractional Form: Express the ratio as a fraction by dividing one quantity by the other. Using the same example, the ratio as a fraction is 5/3.
  3. Decimal Form: Convert the ratio to decimal form by dividing one quantity by the other. In this case, 5 divided by 3 is approximately 1.67.

How do you calculate ratios quickly? To calculate ratios quickly, you can use mental math or a calculator, depending on the complexity of the numbers involved. Here are some tips:

  • Simplify the ratio by dividing both sides by their greatest common factor to make calculations easier.
  • Use decimal or fractional forms for more complex ratios if needed.
  • Practice mental math and estimation techniques to simplify calculations.
  • Use a calculator for precise calculations, especially with large numbers or ratios involving decimals.
