I'll second that. Any idea what your over all theme will be, Acros, mixed SPS, mixed reef?
Start dosing kalk to help stabilize your calcium and alkalinity levels. Once they are stable, magnesium will be easier to stabilize. As soon as they are all on par, start adding.I would caution you from introducing random Pocillopora or plating Montipora. They have a tendency to become weeds and over take your tank. Do not add birdsnests until your alkalinity is very stable, they seem to be the most sensitive to fluctuations.
If your looking for some very hardy Acropora, tricolor valida, red planet, true green slimer, and green tenuis are all very hardy and forgiving Acros. The valida will brown out until everything is "perfect" though. A Montipora that is always fun, valuable, hardy and definitely won't take over(although many wish it would) is setosa. Green Pavona is another good one. Actually, green SPS in general are very hardy.
Like it was said before, hold out for what you actually want, don't burden yourself with corals you won't want in the future.
