just installed 2 250w ushio 20k bulbs in my halide/t5 fixture and moved my old maxspect ethereals to the new frag tank. I noticed it takes several times for these to fire to turn on sometimes. is this normal with new bulbs or just how it is? these are DE bulbs. Can I program these to turn on and off with the apex or will i need some other kind of timer? they are currently 12inch above the water should I raise them as well?
