CroatiaThe article discusses the importance of regularly changing water in a fish tank to maintain a healthy environment for fish. While the water may appear clean, it can accumulate invisible substances over time that harm the aquatic system. It recommends replacing approximately 25% of the water weekly, though the exact frequency depends on factors such as the size of the aquarium, the number and type of fish, and feeding frequency. Some species, like goldfish and larger cichlids, produce more waste and require more frequent water changes. The article also emphasizes the role of the aquarium filter, which houses beneficial bacteria essential for biological balance. Filters do not need to be perfectly clean but should be rinsed in old aquarium water rather than tap water to avoid damaging the bacterial colonies. The goal is to find a balance between keeping the water clean and preserving the useful bacteria in the filter to ensure a healthy aquatic ecosystem.
