About to buy some powerheads, and I would like some advice for a 55g.

When it comes to coral, you can more or less keep any coral in any sized tank. I have a mixed reef that is dominated by SPS and it's only 50G.

If you are looking bubble coral, you'll want to stay at the medium to low end of the flow as they can be damaged by high direct flow. A Vortechs would be good as their flow is pretty diffuse but turbulent, so you won't have any strong direct flow at any one coral. And the fact they can be tuned down is a bonus.
