ideas on setting up a basement sump????

I would recommend planning your plumbing on paper...measure things out...determine what kind of joints you will have in the plumbing, how many valves etc and plug it into the Reef Central Heal Loss Calculator (http://www.reefcentral.com/calc/hlc2.php). It has most pumps in there. What I wish it would do was make a recommendation on what pumps to buy...but since it doesn't do that, you have to do a little research on your own.

Check out this for the head loss curve of various pumps http://www.reefs.org/library/pumps/pumps/ Also, this doc helped me out too http://www.reeflopumps.com/images/f...biased.xls I think for my purposes, a Dart is just the right size for me. It should give me enough power to have the various valves that I want to put on and still give me a little room to grow in case I want to add a frag tank or something later and drive it off the same pump. I also like the concept of throttling back the pump and how that reduces the power draw. These seem to be some of the more efficient pumps that I have read about. I will have 11 foot vertical and 8 1/2 foot horizontal between my pump and the top of the water level. I hope these help you.

You know, as I was typing this, I began to question my own assumptions. I assumed that when you were measuring for head loss, that you measured to the top of the water and not just to your bulkhead. Is this accurate? Should I just be measuring to the bulkhead instead? To me, it makes more sense to measure to the top of the water since that can vary from tank to tank, but I've not ever read one way or the other. Anyone know for sure?

If you were looking for a Dart, here's someone on RC selling one for $150. http://www.reefcentral.com/forums/s...id=1643222 There's also some people selling some Dolphin pumps and other pumps as well. Good time to buy.
