Hi,

Hopefully this is a simple question -- how does the flow rate between
something flowing just from gravity compare to say a 500 gph pump?
Assuming the same tube size.

The reason I ask is I have a veggie filter that is having water feed to it
from a pump and water is returned to the pond via gravity. All the tubing
is of the same size. The pump is putting in more water than my gravity
line can take out. I am trying to figure out my options to correct this.

Thanks for the help

Replace the out-take tubing with a bigger diameter. Your tubing from the
pump has pressure forcing it thru that size pipe/hose at 500 gph, gravity
fed has no such pressure, so tubing must be bigger to allow for more free
flow. ~ jan

Hi Nathan,

Is it possible for you to return the water via a waterfall/stream to the
pond? That would get you aeration, beauty and no flow problems.
Alteernately, go for a 3" or 4" pipe. Lots of extra return capacity is a
great boon.

Our returns are combinationa of falls, streams, and 4" pipe where needed.
Visible on our site below.

Good luck.
