Quick reactor set up question!

I'm gluing my manifold together.

Question: The end of the manifold. is it a must to have water recirculate back to the pump? Or can I just end it?

picture reference. I want to have 4 feeds. Each for a reactor. The plan was to use the last 90 elbow as my last feed line. Someone told me I must leave it open for water to go into sump or else it may back up everything. Is that true? If it is, I'll leave it as open PVC down.

It is open to the sump through the reactors. Key is to regulate the input through the reactors with valves PRIOR to the reactors, not after, to avoid pressurizing them.
