1. What is Degree of Saturation?

The degree of saturation (S) measures how much oxygen is dissolved in water compared to the maximum possible amount at that temperature and pressure. It's expressed as a percentage and is crucial for maintaining healthy aquatic life.

2. How Does the Calculator Work?

The calculator uses the degree of saturation formula:

Where:

• \( S \) — Degree of saturation (%)
• Dissolved oxygen — Measured oxygen concentration in water (mg/L)
• Maximum solubility — Theoretical maximum oxygen concentration at current conditions (mg/L)

Explanation: The formula compares actual oxygen levels to the maximum possible, showing how saturated the water is with oxygen.

3. Importance for Aquariums

Details: Maintaining proper oxygen saturation (typically 80-120%) is vital for fish health. Low saturation can stress fish, while supersaturation can cause gas bubble disease.

4. Using the Calculator

Tips: Enter measured dissolved oxygen and maximum solubility (based on temperature/salinity tables or sensor readings). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is ideal oxygen saturation for aquariums?
A: Most tropical fish thrive at 90-110% saturation. Some species have specific requirements.

Q2: How does temperature affect oxygen solubility?
A: Colder water holds more oxygen. Maximum solubility decreases as temperature increases.

Q3: When should I measure oxygen levels?
A: Measure at consistent times (morning is often best), especially after adding new fish or changing water flow.

Q4: What causes low oxygen saturation?
A: Overstocking, high temperatures, lack of surface agitation, or excessive organic waste can reduce oxygen levels.

Q5: How can I increase oxygen saturation?
A: Increase surface agitation (air stones, filters), reduce temperature, perform water changes, or decrease bio-load.
