You don't need to. You have sufficient light, it just depends on if you like the look of the bulbs your running. I used to run 175 watt 14K hamiltons on my softy tank and I like the "blue" look to them. I also had very good growth with them. If your going to have sps, you may want to use a 10K bulb and then supplement with actinics. You don't need the actinics unless you don't like the look.

Better color possibly, but surely not better growth? From Sanjay's test data, it looks like 14k hamiltons produce about 20% more ppfd on both icecap and HQI(M80) ballasts than the xm20k.
