Well I decided to go with the coralife 30" fixture with the 30" bulbs just due to the fact that it is a little more wattage and also the fact that by the time I change out all the bulbs on that other fixture and add the moonlights I wanted it costs $75 more than the coralife that already has all of those things built in with good bulbs already in it. Turns out the bulbs are good quality and the bulbs and fixture are acually manufactured about 15 miles from where I live. So its always good to support local business! I do also have another 30" t8 fixture I'm going to put a bulb in. I'm just not sure weather to go with a 10k or another actinic. Does anyone know the pro\cons of each option?
