There have been a few posts lately that have got me thinking. Right now I have 2 250w 10k ushios and 4 96watt pc(2 actinic and 2 10k's). I am going to add a 400w halide before I take the sps plunge. What I am curious about is which have better light penetration, pc's or VHO, or are they similar. The tank is a 72" 150gal. , so which would be a better choice, keeping the pc's or going with a couple 6ft VHO's.
