I run all my tank without any actinic suppliments, and I am perfectly happy with it and so are my corals :-)
On my home tank I am running 1X400W EVc 10K, and 2X250W BLV DE lamps in a reef optix III reflector. On the penn state tank we are running 4X400W EVC 10K lamps with lumen arc reflectors.
I yanked out the actincs several years ago and am enjoying the reduction in lamp replacemetn costs and additional electricity costs. The corals are all doing fine and color up nicely.
