Final Lighting Purchase...Which one to get?

[Bob I]

I am not sure if I want to butt in here, but since I have the same setup, I will. To begin with I guess that tank is called a 33 gallon using US gallons? I purchased a used Coralife pendant fixture for that tank (still available here in town for $150.00) It came with a used 175W Coralife bulb. I used that bulb for awhile, and had good success. But because the tank is a bit long for a single 175W bulb, I had a custom built tank made. It is 24x18x18, and better for a single light. I then bought the new Xanium H2 bulb, and installed that afew days ago. Have a look at my site to see what I talk about.
