just a thought about lighting. I searched the pages here and found some good some bad comments about coralife products. Big Als opened up down the street from my place and are using them above their open tanks. The are slim and discrete and just look good. My wife does not want to put a big light above the pond that blocks the window, or a light that is just plain ugly.
in Canada a 72" light is $1300. are there any more inexpensive options that still look good. that is almost the price of a lea and I don't want to disapoint Nic and not put the black ray in the tank.
