Also depth of your tank is important as the light needs to reach the bottom of the tank. You said MH lights @ 6 watts per gal? So you are getting 3 250watt mh lights? I am not familiar with the intensity of MH lighting on a tank that size but I think you will be good.
So, so right, I couldn't commend you more. For a 125G tank (same as mine), a 250W MH will, how do you say, light the freakin' neighborhood? I would suggest going with 4 instead of 3 bulbs to totally eliminate dark areas, but point being, your anemone will be quite luminous. The depth of the tank will be of no concern really, I keep clams on the sandbed, no stretched shells and they grow like wildfire. And oh so pretty
I even have 14K bulbs, so my PAR is naturally reduced, still no trouble.
