How to hookup inlet tube to pump?

[EVReef3]

I have a calcium reactor im trying to get up and running. I have a separate pump (nothing to fancy) to feed the reactor. Now, the problem im having is hooking up the small inlet tube to the pump. This is my first time with a reactor so go easy on me:smile:

What can i get to put in front of the head of the pump to make it small enough to hook the small tube on it?
