If aiming for reef I'd add another 20-40 lbs of base or lr, ditch the circular sponge which will always keep your no3 up, get the equipment mentioned already, get better salt like Reef Crystals or Tropic Marin which are better formulated for reef tanks.
I'd return the damsels as well personally.
Do you know if you want medium or high light corals?
