where to start

[koistudent]

I have a pla for a water fall with stream leading to pond. But at present I am
looking at the equipment needed for this task.

What is the best filtering system and best pump

How big is your planned pond?
What do you plan on having in it?
How high is this waterfall going to be.
Are you on a tight budget?
Post a photo of the planned spot.
