Yep, definitely don't have enough water flow for a reef
tank, if the water level is that low.

I have a new 125-gallon glass tank with a built-in overflow. The
problem is that, even though the tank is level, the water level stays
below the plastic rim of the tank. Is there anything short of
modifying the built-in overflow that I can do to increase the water
level in the tank?

I tried adjusting the level of the water inside the overflow and that
has no effect, and adding more water just raises the water level in
the sump.

What pump do you use? Does it have enough flow ?
Usually, the stronger pump = higher water level in the tank.

Try to find out for how much wate flow is your overflow rated
and pick a pump which delivers flow near this maximum at
a given hight. (flow decreases with the pumping hight)
