centipede output is too strong - want to lessen current

[bacala]

Newbie questions:

We have a Tenecor 150 gallon freshwater tank with a Little Giant water pump with a sump filter and two Centipede. It seems that the fish are always "working"..."swimming upstream" against the current.

SHould there be a centiped "diffuser" to lessen the "garden hose" effect and still not lessen the output of gallons per hour? Or do we want this water turn over ?

thanks in advanced fish buddies

What is the flow rating on the pump? Or...what model LG do you have? When you say "centipede", I'm assuming you're talking about the sectioned returns that can be "bent" to direct flow? Most of these I've seen screw into an elbow at the top of the overflow box. They are usually 1/2 pipe thread. You could make a spray bar from 1/2 PVC to lessen the force of the current without cutting flow too much. Use a 1/2 male adapter and a length of PVC pipe with holes drilled in it and a cap on the end. Or, you could put in several tees instead of drilling holes in the pipe...that would have less effect on total flow.
