i agree dont use shop lights. if you dont want to spend the money for metal halide lighting.. id say go with the coralife aqualight 4-65w set up... i have it and have heard good things about it. and i wouldnt just use any playsand. some playsands will cause alot of algea problems because of the sciliates(sp?) in them.. if you get playsand try and go with southdown or new castle tropical play sands. ohh and i would recomend you get a hydrometer or refractometer to measuse the salinty of you water.. and test kits for amonia, nitrite, and nitrate
