Aquarium Systems WASTE-AWAY Gel freshwater Small, 10-50 l, 2 pièces

Waste-Away-Gel is very easy to use and requires no special equipment. Simply remove the foil, attach the included suction cup, and position the gel in your aquarium or settling tank. The gel releases beneficial bacteria that absorb and break down excess nutrients and organic waste. This keeps the water in your aquarium clear and clean thanks to these cleansing bacteria. Waste-Away-Gel is 100% safe for fish, plants, and corals. Waste-Away-Gel continuously releases beneficial bacteria into the aquarium water. These good bacteria absorb nitrates and phosphates along with organic loads while keeping the aquarium water clean and clear. The gel releases bacteria for a period of about 30 days and changes color to indicate that it needs to be replaced.
