Nice nano, question for you... how high above the tank is the MH, I suspect that since the pics were posted, you have added the 150 W, and am curious about the distance you have yours above the water's surface, and if you have had any problem thus far...(splashes, heat issues) I have a 150 W HQI for a 20 and was told in other threads that it should not be cooled and it was too close to the water surface (~6-7")...I've had no problems thus far, though, just wanted to know other's experiences. Thanks, and nice tank. By the way, you're pretty lucky, as your anemone looks proportional to your tank, as my BTA is 12-14 inches across when expanded, taking up a lot of real estate in a 20 high.
