No we don't have metal halides yet. We have T-5's over our 90 gallon and I have been planning on using 400w halides for the new build but I don't have them in my possession yet. Nate, I know you're not trying to steer me away. You make a good point. That's the biggest reason that I'm nervous about LED- I really know nothing about them other than they're new and starting to catch on and that some people say they look great and work well. On one hand, I feel like well, I'm just gonna end up wanting LED anyway; may as well just go with them from the beginning and figure it out now. Get any issues worked out right away while we don't have too much coral in the tank. But, on the other hand, I know MH works well and I like how they look...
