Before starting, you will have to add water from the opening by putting your left-hand thumb over the hose closing to let the air remove. Now that your siphon tube is, filled with water, remove the hand from the other side to get water flowing into the bucket. Move the siphon along the substrate and, if you have gravel or sand substrate, push the siphon downward to let the fish waste come out with water.
