Which streams for 30g cube?

[30reef]

Roger, I know this has been asked a hundred times before, but here goes again. I have set up a 30g cube SPS only tank, bare bottom. The return flow from the sump is very low to conserve energy. I will rely on the internal powerheads for water movement. Which Tunze streams would you suggest? From the looks of things, I think getting my hands on a new nanostream may be difficult. Are the full sized streams w controller too large for a 30g cube?
Thanks, Keith.

A 6000 could work in a bare bottom SPS tank but the 6055 or a 7400/2 would work just as well, maybe better as it would be a more reasonable amount of flow. You may like the 7400/2 because it affords optional filtration. There are accessories you can add to turn it into a quick filter or run carbon or other media.
