Water Changes
Water Changes are a fundamental maintenance procedure in aquarium care where old water is partially removed and replaced with fresh, treated water. This process is essential for maintaining healthy aquatic environments in both private and public aquariums. It's similar to how air filtration works in buildings, but for water. This task requires knowledge of water chemistry, understanding of aquatic life needs, and careful attention to maintaining proper conditions. When you see this term in resumes, it indicates hands-on experience with aquarium maintenance and understanding of water quality management.
