How to make pump for a waterfall ( height approx. 10cm) and water depth approx 2cm for an aquarium. Answered

I have this aquarium 60x30x30 cm. I wish to setup a waterfall in the aquarium. Now the depth of water in the aquarium is to be approx. 2cm and the height of waterfall is to be approx 10cm. 
I am looking for a pump design which could work comfortably in that water depth.

You need an impeller type pump - volume rather than pressure - a small motor with a flat bladed impeller on the shaft running at high RPM.

Put this inside a container with input/output pipe and your in business.

May be easier to buy from a scrap yard a wind screen washer pump and run it from a wall wart.
