I just picked up a couple more Reef Brites for my frag tank to replace my 250W MH over it (It was a little over kill over a 15x18x12 tank)
I also picked up the mounting bracket for them
Here is the tank with the 250W 14K MH over it
And here it is with the 3 x 15" Reef Brites (Total of 36W 2 x blue & 1 x white)
14K MH
Reef Brites
I also added one over my Freshwater tank
130W PC
48" 40W Reef Brite
I just got them so I do not know how well the coral will do under them but for the frag tank I can add another two Reef Brites if I find that it needs it.
