So im starting an sps dominant tank. The tank is 95 gallons 40 inches long by 20 wide by 30 tall. I wanted to run two 400 Watt Luxcore selectable ballasts with either radium 20k or hamilton 14k bulbs or two used radions G2 pro. What do you guys think is best for SPS in a 30 inch deep tank. Should i go with 250W or 400W. Hope you guys can help and thanks!
