I was just wondering what height they need to be to distribute the light pattern evenly. Is the tank depth on your tank 40" or 50"? (dew2loud1)
They recommend at least 16" from the water, my tank is 30" deep, 40"x50" are the LxW. I have clams on the bottom without a sandbed so penetration is not a problem at all at 30".
