What kind of lighting setup do you have? I know in the tank they keep the acros, they have 400W MH's. And I think they have VHO Actinics in there too.

And do you have a CA Reactor running?

I don't have 400's but I don't have a colour problem with other acros. My problem is it was brown when I got it. When I order from other places and have the stuff delivered it has never been as bad as that piece and the colour comes back the same week.
