I figured if I added more T5s that I might be able to get the same coloring with the Monti's 12-14" away from the bulbs...?

remember, more lights won't increase the intensity, only the spread so there still won't be anymore PAR at 12 to 14" than there is under the bulbs now, you wil just put a more even coverage of the same level by addinbg more bulbs.

ya, I had a 65X turnover with the 6" bedd, but when I upped it to 120X turn over it was insain on the sand bed so I had to keep it in the top 1/2 of the tank, when I got rid of the sand it let me even the flow out over the whole tank. and believe it or not high flow is one of the things that will prevent corals from bleaching from new lights, you just need tones of it.

I'm thinkin a 250w HQI would likely be enough light, especially considering there is dyck all for bulb choice if I go for 400w HQI. My understanding is you get the highest PAR if you use an HQI bulb with an HQI ballast in comparison to HQI w/ electronic ballast or a mogul bulb w/HQI overdriving the bulb...?

Thanks for all your input Steve.

Hmm, I have just been looking at lights myself so here is what I would do if you can only use 1. get a good mogal bulb enclosed reflector pendant. go with a giseman bulb say the 12.5K or "marine" I believe it is called (if AB's were easy to get I would go with there 10K but they are expensive and hard to get). and then run it with a newer style HQI electronic balllast or even better a digital ballast. (newer ones don't under drive the bulbs like the first ones 5 or so years ago did. A mogal based bulb will give you more coverage than a double ended will. actualy I believe there is some one on the board selling electronic ballast and mogal pendant for 75 bucks each but I am not sure what kind of ballasts they are. If you are using a hood you could use a retrofit reflector, but I mentioned the pendant style as it will be a little less heat.
