wanyer are you saying tha you have been lighting your tank with a single 400 bulb .so i guess that i single 250 would light a 75 gal foot print then.

Mike:

My tank is only 3 feet long, a standard 75 would be 4 feet, so, if your keeping sps & clams, I would definately use 2 bulbs.

thanks Wayner I thought that the tank was 4FT long.
