lighting ?

im picking up a new 125 gallon tank on monday yippee so will need more lights :-(

now ive seen this a few times already and wonder what are the advanages to lighting a 6' tank with a 400 watt in the middle ans 2 250 watts on the ends? are there any or is it just a preference?

I believe it has to do with metal halides only having a certain span of it's light. If you only had the 400 watt in the middle it would be inredibly bright with the sides of the tank being dimmer. Boy I wish I could have a setup like that!

Form what I have read, you will get much better light distabution from hanging two 250 watt lights. Less shadows you do not have to hang a single light over the center brace of your tank. Plus, you get 100 extra watts going with two 250s instead of one 400.

I suppose it could be argued that the 400 will give you higher intensity for the corals that really love light while the ones that don't need such intense light could go on either end under the 250's. If we were talking about a deep tank, I might go along with that to a degree. In a 125 though, I believe you will have more than enough light with a 3x250. You will also have good coverage with three bulbs over the 6' tank. JMHO.

Alot of people run a 400 watt 20K in the middle and 250 10K's on the ends. Reason is that a 20K gives off less PAR than a 10K so the extra wattage makes up for it.
