Ok, so my 400watt halide bulb SE is beginning to change, so i figure i need to replace it soon. :( Right now I have a 400 watt coralvue 20k. My growth isn't very good though. I thought about a 10k bulb, but I don't care for the yellow look. Also on my tank I don't have room for any actinics. So does anyone know of a good 14k (around there) 400 watt halide that can replace it and still get good growth and color? Also what are some good online retailers to order one from? tia
