It wont need to be much at all. If it's just from the bottom of the tank to the top of that ghost wood (about 18"?), you could probably get the smallest pump on the market and make it work. Its hard to come up with a GPH number for you, just measure the height you will need the water to travel up thru the tube (to the top of the watefall) and use that when you choose your pump by looking for the max head height. Also, it depends on how fast you want the water to go, for just a small trickle, go for a pump with a max head height just a few inches above the height you will need, or if you want Niagra Falls, get one rated much higher than the height you need. You could always adjust the output to be slower if you need to, so more powerfull is always better to start.
