I run 4 t5s (2 actinic+, 1 aquablue, and 1 GE daylight), and I have noticed that almost all of the sps I have bought have become lighter in color. In general, they seem to improve when raised in the tank (which seems counterintuitive to me). One example is a green cap that I bought and placed quite low. It became quite light in color and eventually started to recede. I raised it up a lot and it turned around and started to grow. I am adding two more t5s, and I think I will head toward a bluer spectrum, so we will see what that does.
