So I've had this purple lobo since January. It came with real nice green and red highlights. Well over time those highlights are almost gone and it's a light purple instead of the real dark purple it came with. It's on the sand under an Ati 4 bulb fixture. Tank is a 75 gallon. This is not a branching type by the way. Any ideas what could cause this? Alk is about 8-9, 1.025, cal 420. Is it possible it needs to be shaded?
