Basement Sump Question

[BCashion]

Quick question for those folks with a basement sump:

Is there a problem with excessive turbulence (as the water enters the sump) resulting from the height differential?

I'm planning a sump which likely be 12 feet below my display tank: seems like the water would pick up enough speed that it would cause quite a bit of splashing as it entered the sump.

If so, what have you done to circumvent this?

You could use elbows to make "steps" so the water doesn't fall the entire high at once.

and/or you can have it dump directly into a closed box with holes drilled in it to contain all the splashing.

I've used a piece of 4" or 6" PVC suspended a couple inches off the bottom and extended around 1' up past the water level. It keeps the splashing down and works as a bubble trap.
