Sump equipment

6 feet? Is the sump in the basement? head loss is determined by upwards lines and elbows (90's and 45's), not any lines parallel to the floor. Water traveling sideways isn't effected by head loss.

Hey, I take offence to that. Not really. Mine is over 6' plus 1' for the 90.

I just upgraded to a DC pump, and it has 6 variable speeds. I LOVE IT! Cheaper than AC pumps now and AC pumps can't do variable speed.

I was told that the fuge need slower movement.

That's not true at all. I'm wondering why this was suggested to you. Why did they say it needs to be slow?

I'm not sure why they told me this. They just said a slower flow through the fuge works better. I don't know since this will be my first one.

But the overflow I plan on getting is rated at 600 gph so I'm going to get a pump rated a little more then that an I'm going to put in a ball valve

600 gph isn't much for a 90 IMO. That said, there is no legitimate reason why you would want slow flow in the refugium. Some people say that the macroalgae needs "dwell time" in order to draw nutrients from the water, which is total nonsense.

Ok that's good to know
