Final answer:
The recommended pH level range for a saltwater fish tank is between 8.0 and 8.3. This mimics the natural seawater environment and is crucial for maintaining a balanced and healthy ecosystem for marine organisms.
Step-by-step explanation:
The recommended pH level range for a saltwater fish tank is Between 8.0 and 8.3, inclusive (Option B). This range is optimal for marine organisms to thrive, which is crucial for a balanced and healthy aquarium ecosystem. The pH scale is a measure of how acidic or basic a solution is, with lower values being more acidic, higher values being more basic, and 7 being neutral.
Since seawater typically has a pH near 8.0, saltwater aquariums should aim to mimic this environment. Maintaining the correct pH is important for the fish and other marine life in the tank because it affects their health and biological functioning. Regular monitoring and adjustments may be necessary to keep the water parameters within the proper range.
