Siphoning is something that alot of fish keepers initially struggle with either struggling to get the siphon started or over siphoning and ending up with a mouth full of dirty fish water, the project is designed to be extremely easy to use. if you are comfortable with siphoning then you can use the siphon as normal but if you are someone that struggles when starting siphons then, you can attach the PVC hand pump to the siphon hose and draw the handle up pulling the water down the tube and begin the siphon this way, when the siphon has started you can easily move the hose through the gravel waiting for the level in the tank water container matches the level in the freshwater container, when it does remove the siphon from the water to stop the siphon.
