The video shows a fish tank with a green hose attached to it. The hose is connected to a water filter and is pouring water into the tank. The water is flowing into the tank from the top of the hose, creating a stream of water that falls into the tank. The tank is made of glass and has a sandy bottom. The water in the tank is clear and there are no fish or other objects visible in the tank. The background of the video is a beige wall.
