94 gal, 36X24X25
two 250 watt HQI ballast (advance M80 tar) lighting two Sun Aquatics 10000K SE 250 watt bulbs. for actinic I run two 36" Uri Super actinic VHO run in series off a workhorse 7 ballast which is set to over drive them about 10%.

I run the actinic 14 hours a day and the MH 10 hours a day in the winter and 12 hours a day in the summer.

am I happy with it, yup, I just wish I would have went strait to this be for fooling around with other styles of lighting.

It all exists in a DIY hood that I DM (did myself) :cool:

It has been up and running for ~ 48 hours but so far so good. definately brighter that the 4 PC's I had before... all the coral seems to like the brighter lights :biggrin:

54 gallon corner bow front, pretty tricky to find lighting that fits over it.
1 250watt 14k ARC MH.
2x65 watt PC with custom remote balast
1 10000k
1 380NM actinic

Actinic on a 10am
MH on at 12pm
MH off at 4pm for cooling
10K on at 4pm as substitute
10k off at 5pm
MH on at 5pm
10k on at 7pm for prime viewing and feeding
MH and 10k off at 9pm
Actinic off at 10pm

I also get a couple hours of indirect natural daylight which aids in dawn lighting. Because of the shape of my tank I think my lighting is very well suited and I don't think I'd change it at all.
