Those pumps you point out... I don't think they are even DC, they are still AC, I think the DC pumps which I don't think are even available to the masses (or the rich masses) are even more expensive.

When someone states that you shouldn't flow so much through a skimmer, there has to be many considerations. What type of pump is it? Is it a pressure rated pump or flow pump?
Always remember that you aren't really flowing 1500 gph through your skimmer as the beckett drastically drops that flow rate down. I think if your pump flows 1700 gph at 0 ft. head and it something like a Iwaki 70rlt, then I'd say that even then, you would be able to run it, although you might want to drop that flow down a little bit and divert some of that flow elsewhere.
If that 1700gph is something like a flow pump, like a mag 12 or even a mag 24 (of course it's not because those flow different numbers, but I'm just using them as examples), I would not divert flow anywhere.
It all depends on what type of pump you are using my friend.
Peace,

Its a pressure rated pump. So would I be good if I used a Y fitting and used one to go to my return and one to my skimmer?

Yep, just make sure you put ball valves on each line so you can control the flow through each since flow always goes down the path of least resistance, you don't want the return line to rob all the flow from the skimmer since the beckett causes quite a bit of resistance to produce it's venturi effect.

Gotch ya. I have an extra 1" gatevalve that I am going to use on the skimmer side and I will put a ball valve on the reutrn side.
I figured having less water flowing through the skimmer would be beneficial as well. Wouldn't that mean more time for the bubbles to be in the skimmer?

Yes, to put it succinctly.
Dwell time is important, but honestly, the best setup for that is a recirculating setup where you can control flow independently as well as take water from the overflow and run it to your skimmer.
Dwell time can be increased in a non-recirculating model by making the skimmer bigger. That's about all you can do really or slowing down flow to the skimmer, but that becomes a problem when air injection and flow through the skimmer are coupled.

Rgibson,
My old beckett skimmer had no bulkhead fittings, it's just 40" of 6" tube with uniseals on it for penetrations. Take a look at it in my gallery.
My new NW skimmer is also very similar and made by Spazz here on RC. It has spears unions welded to the skimmer body for inputs and outputs as well as recirc. pumps.

weld on 16 I believe, at least that is what it looks like to me.

Well, the unions have been cut in such a way that it actually molds to the exterior of the tubing and is then welded on. The unions then have a short little PVC pipe protruding from them, but the PVC pipe is not welded to the cast acrylic tubing in any way.
Don't ask me how he does it, but that's just how he does it.

Here are some links that have some information about it.

Thanks for the info on the U-tube, that's been a big concern for me Im going to be using a MR-4 in the sump, maybe I can eliminate some of the extra baffles that I was going to add to the sump.
Do you think I could use my Hammer head to run the skimmer and the return for a 476g tank?
