Actually the mag 9.5 was use may be half a day. I used it on my 75 gal and it was way too strong, drove down to LFS and got me a quite one that same day. You can take it a part if you like to see how much wear and tear it has....
The Metal Halide bulb I'm not sure how old it is.
I'm setting up a 150 gal and need to sell some of this stuff to offset the cost of the new tank....
Heres the cube.......I may sell an unfinished hood 61x25x15 if anyone is interested.
