Fantastic lights and great for SPS...assuming you get enough for your particular set-up. I have a client running 1 on a 90 gallon cube and his tank is looking great. The tank is 24x24x36. What size is your tank?
thanks
my tank is 49 inches long about 13 inches wide and around 20 inches in height
its not a small purchase so i need to be sure if one is going to be enough
