I agree with rallysman. I use a check valve AND I drill the holes in the return line. Anything to full proof the potential hazards of a 240g water spill in my living room.
Anti-backflow for sump return?

A bigger sump might not always cure the problem. If th return is half way down in a 300g tank, it'll overflow a 150g sump.
Drilling a hole right below the water surface is cheap (basically free) insurance. Even if you don't "need" it, it's still a good idea.

You know as I re-read the first original post I finally caught the word "REEF" as in saltwater...salt-creep will foul a swing check valve as well as a dirty line in a freshwater system.
Rallysman got the solution, 2 holes just below the surface to break the siphon.
Sorry my bad...

I have even used 3 holes to make sure. But durring regular maintenance you can just check to make sure that the holes are still working. Basically once a month your going to turn the sump pumps off and see if the syphon breaks work.
