Siphon filter

[2007PSanHa]

Was wondering when I was cleaning my tank the other day whether anyone had tried making a filter with a siphon. Instead of electricity powering the filter it would be a siphon. It would save electricity and be less noisy! Has anyone ever tried? Thanks!

Unless you can redefine the laws of physics, it isn't possible.

How come?

A siphon need a drop from intake to out take to work. How would you get the water back up?

You can siphon the water into a tub or tank below the aquarium and run it through plants and rocks and other filter media and the pump it back up the other side... but the siphon would not work

My filter is above he water

Then try it and when it doesnt work dont blame us

My filter is above he water

Regardless whether the filter is on top or bottom you would still need some way of moving the water up.
Even if this were possible without some sort of mechanical/electrical pump (I'm not saying it is) I don't think you would have a high enough water turn over rate for it to be very efficient.

Now I've confused my self! Ill give it ago but I guess it won't work!
