Plenum: from what I read It sounds like its just a raised platform so that
there is water below the sand level.
Would a capped,un-connected undergravel filter be suitable to use as a
Plenum?
I havent set my tank up yet so I still have time to do this.
Is using a Plenum better than not using one? If so, why?

thanks for all

Plenum is old news. That was the modern method 12+ years ago when I was still
running my 150 with an undergravel filter. Deep sand bed with live rock is the
way to go.
