How long is the 33 long tank? You want to cover the tank end to end so there are no significant low light areas. 200 watts PC with a 10k bulb and blue actinic should work for you. I add trace elements, iodine and calcium regularly. I also feed my anemones a small peice of raw shrimp 1 to 2 a week. I keep the hardy type anemones ( condys, bubbletip, flowwer). My coralife aqualights are dual bulb in a reflector to max light down into the tank.
