Prime HD over 35g cube?

[mikee002]

in the process of setting up a 35g cube, 20x20x20. Will a prime hd be enough for this size tank? It’ll be mixed reef stocked. I know a hydra 26 hd would probably be ideal, but saving $$$ where I can get away with it would be nice.

I have a prime HD on a 29 biocube and on an Innovative Marine 40(which Is close to a cube) and so far it's been sufficient.
