1. What is a Spawn-to-Substrate Ratio Calculator?

Definition: This calculator determines the ratio between spawn weight and substrate weight in aquarium setups.

Purpose: It helps aquarium enthusiasts and professionals maintain optimal conditions for aquatic life by ensuring proper biological balance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Spawn-to-substrate ratio (dimensionless)
• \( S \) — Spawn weight (kilograms, kg)
• \( Sub \) — Substrate weight (kilograms, kg)

Explanation: The spawn weight is divided by the substrate weight to get the ratio, which indicates the proportion of biological material to base material.

3. Importance of Spawn-to-Substrate Ratio

Details: Proper ratio calculation ensures healthy microbial activity, proper nutrient cycling, and optimal conditions for aquarium inhabitants.

4. Using the Calculator

Tips: Enter the spawn weight in kilograms and substrate weight in kilograms. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a good spawn-to-substrate ratio?
A: Typically between 0.1 to 0.3, but depends on the specific aquarium setup and species requirements.

Q2: How do I measure spawn weight?
A: Weigh your biological material (spawn) using a kitchen scale or similar measuring device.

Q3: What substrate should I use?
A: Common substrates include gravel, sand, or specialized aquarium substrates - choose based on your aquarium needs.

Q4: Can I use this for saltwater aquariums?
A: Yes, the calculation works for both freshwater and saltwater setups, though ideal ratios may differ.

Q5: How often should I recalculate this ratio?
A: Recalculate whenever you add significant amounts of spawn or substrate to your aquarium.
