Closed loop manifold piping question

[Reefbox]

Are closed loop manifolds run under the top brace or should I drill small holes in the top brace and hang it below the top brace?

This will be 1 1/2" pipe with about 12 ports powered by a Sequence Reeflo Hammerhead.

Thanks for any advise.

The final outcome will be the same so it's really up to you.
