Im searching through the forum and read that both brands are good quality sump pumps for the $$$. now i need to figure out which one i need.

At 5 feet head, each pump has a GPH of:

Mag Drive 12 = 1120
Mag Drive 18 = 1200
Quiet One 6000 = about 1100?

i will be using a 72x30x24 tank with two 2" bulkheads; one in each upper corner. the wet/dry sump i will be using will be about 67 gallons and calculated about 5 feet of head (give or take a couple inches). I want anywhere from 900-1200 gph.

i will just run PVC pipes from each drain down to the sump. still a little confused but If i calculated correctly using Chompers' chart (http://www.monsterfishkeepers.com/forums/showthread.php?t=205645)... i should be getting about 1500 gph total from both drains. am i looking at the right return/sump pumps? if not/yes, what do you guys recommend?

this is my fist monster tank so im wondering if i went a little overboard with the drain holes by going with 2"x2?
 
Yes, 2 x 2" drains is a bit large for 1200gph, but it will be fine if that's what you want.

Overall, I would go with the Quiet One. I honestly think they are quieter that the Mags.
 
I run a Quiet One 6000, and it is a very quiet pump. I also run a mag-drive 7 on the same tank, and they are comparable in noise, the quiet one being the better of the two.

Id get the Quiet one if i were you.
 
The drains will only drain what you overflow the tank with...
it's not like they are going to drain "MORE" than what the pump puts into the tank...
they are just the overflow plumbing,
and what the pump put's into the tank is what is going to "OVERFLOW" into the sump...
Having a larger size drains are just like insurance against possible plugging or buildup of Algae...
So 2 x 2" will easily handle the flow from a QuietOne 6000.

also look into 2" flexible hose, like Pool cleaning hose, (NOT PVC) it will be quieter than the hard PVC pipe and you won't need the 90's to get to the sump....the gradual bend of the hose will flow the water more quietly to the sump...
 
I'm just error about it drainig too fast and making the sound of the overflows being too loud.

would these flexable hoses connect to the bulkheads or would I need some adapters? somthing I can find at home depot or lowes? just did a quick search and that looks easier to install too. will go check out home depot/lowes this weekend to see them in person.

Edit: Dumb question but can I install a ball valve/union on a flexable hose? (or is there an equivelent?)

You want it to drain as fast as possible, why wouldn't you?

2"Flexible hose, needs 2" hose barbs...

I still think you are not understanding how this system works...
If you want slow draining then you fill the tank with a slow pump
The Tank is only going to OVERFLOW what the pump puts into the tank...

if the overflows are slowed down by anything valves, what ever, and the pump is pumping water to the tank...where is the water that the overflow has been valved down, going to go?

Yes, ball valves and/or unions can be installed on flexible PVC. A tip for flexible PVC gluing: Don't use the primer type solvent then the PVC cement/glue. The primer softens the flex PVC too much and takes longer to dry causing possible leaks in the joint. Go with the one step method with the PVC cement only. I use Christy's red hot with out the primer.

When connecting flex PVC to bulkheads on the side of the tank I like to use a 90 to get the initial bend out of the way then attach the flex PVC to that 90. Less stress on that joint. The flex PVC will have a slight curve to it so you can have it gently curve from the 90 and drop down under your tank and go directly into your sump.

^^^^ I agree!

The larger the drain the better. It's easy to add another pump if needed when stocking grows/changes.
Don't put valves on your drain. The water will just keep rising until it spills over the sides of your tank.
