My Fish Tank

The water in my fish tank is dirtyI need to clean my fish tank. I use a net to take out my fish. I put them in a bowl of clean water.

I take out the rocks and plants. How will I take out the dirty water?

I can use a siphon. I fill a rubber tube with water. I pinch the ends of the tube. I put one end of the tube in the fish tank. Then I let go of that end. I make sure the tube stays under the water.

I put the other end of the tubeinto an empty bucket. Then I stop pinching the end of the tube. The water flows out of the tankand into the bucket.

My fish tank is now empty. I clean the rocks and plants. How will I put clean water in the tank?
