The 130 stock is usually pretty limited to SPS with lower light needs - such as Seriatopora and Montipora and possibly a few others. As bhazard said many of the acros tend to lose color, turn brown, and just don't grow as quickly as they do under better lighting. Bulbs need to be replaced about every 6 months if trying to keep acros and other SPS under the stock T5/PC bulbs.
From Red Sea on the 130 & 250 lights:
"In long-term tests we conducted on the MAX 130 & 130Din our laboratory, the system proved capable of supporting all soft corals (Sarcophyton sp., Lobophytum sp., Sinularia sp., Xenia; Cladiella sp., etc.), all LPSs (Large Polyp Scleractinia, like Euphyllia sp., Plerogyra sp., Nemenzophyllia sp., Trachphyllia sp., Caulestra sp., etc.), some SPSs (Small Polyp Scleractinia, such as Stylophora sp. and Seriatopora), sea anemones, all types of crustacean (cleaner shrimps, peppermint shrimps, hermit crabs, scarlet hermit crabs), sea stars and giant clams (Tridacna sp.).
The Max 250 has been designed specifically to be capable of supporting even the most delicate SPS corals, and offers no limitations other than the physical size of the aquarium."
I tried a pink stylophora under the 130 stock lights once - up on top. A small frag stayed pink but never grew, a larger pink colony browned out and never grew.
