When I transferred my 30gal reef to the 55gal that was given to me I simply put my existing lighting over the top. I would love to purchase a 48" set up similar to the one I have but my 36" is only 2 1/2 months old. If anyone were interested in my 36 I would be able to move forward in purchasing a new, better fitting light for my new set up. Is anyone interested in upgrading their lighting? $80 takes it. Like I said, nearly new. Plenty of life left on the bulbs. One cord, one timer, 3 sets of dual blue led's for moonlight shimmer. Perfect for a 36" tank.
