水變混濁有以下兩種情況：生態系統建立初期（首 1-3 星期），當微生物開始出現並繁殖，魚缸內的水便會變得混濁，這是正常現象，只要用戶不要換水，待生態系統完全建立之後（約 3-4 星期後），水便會回復清晰。過度餵食魚糧也會令水變濁，因此每次餵食時，要確保魚能在 90 秒內食完魚糧，水便會不易變得混濁。Turbid water has the following two situations:
It is normal for the water in the aquarium to become turbid as soon as the microbes begin to appear and multiply in the early days of the ecosystem (first 1-3 weeks), as long as the user does not change the water until the ecosystem is fully established (about 3-4 weeks later), the water will be clear.
2 Excessive feeding of fish food can also make water turbid, so each feeding, to ensure that fish can finish eating fish in 90 seconds, the water will not easily become cloudy.
