Nutrafin Waste Control – Biological Aquarium Cleaner reduces aquarium maintenance by efficiently breaking down waste in gravel, filters, decorative features, and on interior surfaces. Its unique biological formula rapidly decomposes organic waste from overfeeding, fish waste, and decaying plant material. Ideal for goldfish, cichlids, and densely populated tanks, Nutrafin Waste Control helps manage large amounts of fish waste. Note that ammonia levels may temporarily increase during the breakdown process. To mitigate this, we recommend using Nutrafin Cycle Biological Aquarium Supplement concurrently to control ammonia and nitrite levels, ensuring optimal water quality and a clean aquarium environment.
