  Cloudy water in your Fluval Other tank often occurs when the biological balance is establishing itself, or due to overfeeding. To resolve this, perform a partial water change (up to 25%). Add a dose of Nutrafni Aqua Plus Tap Water Conditioner and Nutrafni Cycle Biological Aquarium Supplement. Reduce feedings to once every two days until you see improvements. If the problem persists, have your aquarium and tap water tested at your local pet store.

  Green water in your Fluval Other tank is caused by algae growth. To prevent this, remove your tank from light and use high-quality fish food. Perform a 25% water change every 4 days. Reduce feeding, use high-quality fish food, and dose with Nutrafni Cycle Biological Aquarium Supplement, as well as Nutrafni Aqua Plus Tap Water Conditioner with each water change. If the issue continues after three weeks, the green water might have another cause.
