How do I properly use a fish tank siphon to clean my aquarium?

To properly use a fish tank siphon to clean your aquarium, start by placing one end of the siphon tube in the tank and the other end in a bucket. Suck on the tube to start the flow of water, then gently vacuum the gravel and remove debris. Be careful not to disturb the fish or plants too much. Repeat until the water is clean and the tank is tidy.
