Mag 18 or 24 would do the trick. I'd get a 24 for that run.

Yes, moving water sucks big time!!!!!
it just might already be on the way... return, resale?? relax??
Return. If you can't, it won't be hard to resell. If it is hard to resell, relax. Have a drink. But whatever you do, figure out a way to not have to carry buckets of water. Nothing kills a reef tank and drives a person out of the hobby faster than carrying buckets of water. (namely because you give up carrying buckets of water, the reef tank becomes a cesspool and then you find another hobby.)

How much head pressure a horizontal run creates is a complicated problem, and the 10 ft = 1ft isn't really accurate anywhere. (Dynamic head pressure is largely caused by friction and turbulence, and is proportional to length And velocity and the inverse of pipe radius squared)
What is true here though is that pipe diameter is incredibly important at this sort of length, and once you get a pump that can handle more than about 12 ft of head pressure, increasing the size of the pipe will do more for you than increasing the size of the pump.

Unless he buys something like a jet pump, he's not going to get much more than a trickle. There's just too much friction over 75 ft of 1/2 tubing to move much water. And as you try to push more water through, dynamic head increases exponentially.
Just go and buy 100 feet of 1" black poly water supply line.

Play around with this if you want to understand how this stuff works
As an example, moving 600gph through 75 feet of 1" tubing and up 8 feet creates 13 feet of dynamic head.
Switch it to 1/2", and that goes up to 160.

But it'll actually work.
A bigger pump won't get him meaningfully more flow. It'll just cost him a bunch of money upfront and more money every time he turns it on.
A mag24 isn't going to get him any more than a mag 12 is.
No, I get it. It just sucks.
On the other hand, carrying buckets of water up a flight of stairs for every water change - if you can't pony up the money for the pump and the proper hose / tubing, you might as well get out of the hobby now. 'Cus in 2 months, you'll give up on the water changes and the tank will die a slow death.

I use a Compact 3000 to pump water from my RO drum 65' to my sump room, and then the other way to pump old tank water to the toilet.
I use 1/2" food grade pvc hose.
Takes about 20-30 mins to pump 25 or so gallons, but I don't care. Saves carrying buckets.
Hope that helps !!

I'm pretty sure I'm just going to get a little bit in the hose and blow through the rest to get it in! haha, seriously though thank you all for the info. since I ordered it I'm going to try the pump, but I'm going to chalk it up to a learning thing. I do have about 20 other uses for the pump if it doesn't pan out (I'm telling myself this).

That is an awesome calculator. Ty for linking that. Just measured the flow of my pond (mag18) and its dead on to what the calculator says.Play around with this if you want to understand how this stuff works
