should i make a plenum

[old hermit]

ok i cant make one in my 29 gal. tank but im building a refugium in a 10 gal. tank so should i put one in there. will it help at all or just leave it out. i want the refugium for pods mainly and to help with nitrates.

I had one in my 55 gal before I set up the 100.
I really thing the DSB is a better way to go, IMO.
It's easier to set up, it looks better and I think it works better. Even tho they do the same thing.

Is the question about a plenum or a refugium?
If plenum, then no they are not needed. IMO, DSB works very well.
If refugium, then, for what you are trying to accomplish, I would say yes. It wouldn't hurt anything.
