• Depth: Aim for a minimum depth of 3 feet to provide stability in temperature and protection from predators.

Water Quality Management

Health Monitoring

• Regular Checks: Monitor your koi for signs of illness, such as changes in behavior, appetite, or physical appearance. Early detection is crucial for effective treatment.
• Quarantine New Fish: Always quarantine new additions to prevent disease transmission. A quarantine period of at least two weeks is recommended.

Seasonal Care

Bacterial infections can occur due to poor water quality or physical injuries. Symptoms may include red lesions, fin rot, and lethargy. Treatment typically involves improving water quality and applying antibiotic treatments.

Fungal Infections

Fungal infections often manifest as white, cotton-like growths on the skin or fins. Maintaining water quality and applying antifungal treatments can help resolve these issues.
