It's called head pressure and most sumps have it. Most sumps return up the back of the tank. The only thing to take into account is that for every foot of height, you lose some of your gallons per hourof pressure from the pump. I don't know the formula to figure head pressure loss but if yours works then I wouldn't worry about it. It is fine for vertical line return.

Reference the pump manufacturer for the affects of head pressure on your particular pump. Each pump will handle the head pressure differently and have its own max head height before the pump cuts off or just doent push water any more effectivly.

since my return line is vertical, do you suggest the mag9.5 instead of the mag7??

How high is your head? What is the capacity of your overflow in GPH? Both of those will be factors in determining your sump's pump size.

If you can try to get some reef rubble from your lfs, you can scratch the bio balls. This will save you grief down the road. You can even buy reef rubble for pretty cheap. I took the bio balls out of mine and replaced with reef rock. Since then, I have not had a problem with Nitrates at all.
Lando can vouch for this method as well.
