I've been using a Mag 18 on my 58 gallon, and I was running it through a chiller. What surprised me is the measured flow out of the pump. I assuming I had between 8 and 10 feet of head (including the chiller), and one day I was curious how much water was flowing. I drained about 4" of water from the display into the sump, then timed how long it took to fill the display back up. After calculating the volume, the actual flow from the pump was around 450gph. More interesting is that these pumps actually draw less power when in high head situations (it was pulling on 61 watts, instead of the rated 120).
Since, I've read a few places that you should actually double the plumbing on mag pumps to achieve the rated flow (so for this pump, with a 3/4" outlet, i need to double the plumbing to 1.5" with a bushing). I've yet to do this, but hopefully I'll have success when I get the new tank set up, as I'd like to use this pump (it's a 156, which is a foot shorter than your tank).
Anyways, not really sure if this helps at all, but if you decide to stick with the mag12 maybe this will give you some tips on maximizing the flow.

sorry... but HUH???? I am completely dazed by plumbing talk and water volume and head pressure and flow and.... and.... and.....all I know is the water has to flow out and get back up and in somehow...
So bottomline... which pump should I either use that I already have OR which external pump should I look into getting$$$$$

If you already have the mag 12I would use it. If it doesn't do what you want then look for something else.

Sorry! My enginerding side comes through every now and again. 
I'll try to sumarize my point. The mag 12 could be a good solution, but youll need to make sure that your plumbing is not overcomplicated. If you have too many bends, angles, Ts, etc., the mag pump is going to loose a lot more water flow than an external pump.
Since you already have it, I'd recommend starting with that, ask around for help when setting it up, and then, should you determine it's not enough, you could upgrade at a later time.

Jenni- have you looked at pump flow curve chart?

Geoff...
If I have looked at it, I probably didn't even understand it...I'm telling you guys, I am plumbing challenged...I understand the basic concept...water flows out, water is pumped back up...as far as gph, head pressure...etc etc...I am clueless....

ok, lets look at some pump charts then. 
here is a real simple one to understand. find the pump you have, the Mag 12, measure how high the top of the tank is from the floor. find that on the chart. now follow the line to your Mag 12 column. this is about how much water the pump is pushing.
this is just going to be optimistic though. any elbows or valves will cut down the flow a little bit.
if you really do not care to know how to read a pump curve that is fine, you can ignore me.

well, if I am "understanding" the chart... I figured about 5 feet up for each return (so that would be 10 total... right?) it seems that the mag 12 would only be pumping 600 gph... so that is no where near enough, right??? How can anyone with this size tank use it effectively? This is driving me crazy....what should I do?

Big B...
you said you are using the same pump on the same tank..... how did it work for you...I am reading the flow chart correctly... would it be pushing 600 gph to each return or is that the TOTAL it would be pushing?
I am getting dizzy thinking about all of this pump stuff...

Jenni- you are trying to hard. slow down.
the pump is only pushing 5 feet of head not 10. you do not add head pressure that way when dealing with vertical lift. it is 5 feet worth of head pressure regardless if it is 1, 2 or 10 returns.
you will only be running one pipe up to the top of the tank anyway. when it gets to the top of the tank is when you split it for the two outlets.
does that make sense?
