Yeah, if you've got a dual 250W MH w/ 6500K lamps you will want the actinics not only to increase the spectrum available to the corals, but also tame down the yellowish appearance of the 6500K lamps. The up-side is that the 6500K lamps are VERY bright compared to higher K-rated lamps and an excellent representation of natural sunlight. A pair of NO actinics on a cheap Home Depot ballast would work fine, and you could upgrade to the Icecap and VHO actinics down to road if you wanted.

Did I mention I'm jealous?
