Nope i have it to... I have a chalice that is now basically white with a small amnt of pink on it. I had it in the nem tank under a 250 halide and now is in with the t5's. No problems with the halide.
So i can agree with you on this. I have no idea what is going on.
I am gonna have to find the chalice a new home as i can't put it in with the nems...
