I would stay away from SPS and clams. It can be done with PC's but I've seen enough people with failures to recommend it.

I'd like to try a clam and at least one SPS. I could build a new hood and put in a MH lamp, I guess. I dunno, it seems like there's a lot of superstition about lighting. Fluorescent lamps are not much less efficient than metal halide, per watt. Light power falls off with the square of distance, so having the lamp close to the water and the animal close to the light does a lot.

You'd be surprised how little light some clams need. I have a crocea that has basically been shaded for over 6mths. Its doing fine, just as well as the other clams I have. I think in your case its more about stability than light. I believe a lot failures that people attribute to light are probably b/c of instability in tank conditions instead.
