Aquarium Fertilizer Calculator

The Aquarium Fertilizer Calculator helps you determine the right amount of liquid fertilizer to add to your planted aquarium based on the tank size.

Formula

$$
\text{Fertilizer (mL)} = \frac{\text{Aquarium Size (L)}}{10}
$$

Where:

  • Aquarium Size is measured in liters (L)
  • Fertilizer is the recommended weekly dosage in milliliters (mL)

Example Calculation

For an aquarium with a size of 50 liters:

$$
\text{Fertilizer} = \frac{50}{10} = 5 \text{ mL per week}
$$

How to Use

  1. Enter the total size of your aquarium in liters
  2. Click "Calculate" to get the recommended fertilizer dosage
  3. Add the calculated amount of liquid fertilizer weekly

Tips for Aquarium Fertilization

  • Start with less: If you're new to fertilizing, start with half the recommended dose and increase gradually
  • Monitor plant health: Adjust dosing based on how your plants respond
  • Consider fish load: Heavily stocked tanks may need less fertilizer due to natural waste
  • Test water parameters: Regular testing helps you fine-tune your fertilization routine
  • Consistency matters: Regular, smaller doses are often better than large, infrequent ones
