Agreed - Nothing while the tank cycles, you want dissolved protiens to fuel the inital nitrogen cycle. However your flow rate is still off, like I said get 2 hydor circulation pumps each rated for 100 gal per hr saltwater. Attach them to the sides of the tank facing each other and the rockwork. I would upgrade the HOB to a HOB skimmer but that's just me, not really needed for fish only. If you stick with the HOB, after the cycling add Purgien or Chem-pure Elite for chemical filtration so as the HOB isn't just an oversized Powerhead with the wrong type of impeller construction for saltwater.
agree with this, a couple of small power heads and hob skimmer plus live rock and your filtration is complete, the skimmer will help keep your will water clear
