How to use: First immerse the gravel siphon in water, outlet up, quickly use hands to knead and press the balloon the ball a few times until the water overflows from the mouth of the tube, and then place the outlet down into the container. Changing water is important. Keeps the aquarium clean, gives your fish a nice living environment. Practical style, it can be free to disassemble and clean. Note: When used, the water level should not be too low! As for secondary use, water in the hose must be drained out. (Package include: or 1X change pipe clamp or 1X 1m12mm extension tube)

I had to altered it cut the long stim off about half way. I got it to pull water over the top. It is working now like it should.

Pieces do not fit together and there are no directions on how to put together. The directions for use are written in broken English with misspelled words. Do not buy this.
