Question about 2 Chalices

[BlazinNano]

Back in April my fiance bought me a frag of Big Pimpin and Lime In The Sky Chalices. They both are doing good eve though they are growing slow....lol But my question is my Big Pimpin is loosing some of its blueish color and starting to get a little reddish/brownish fade to it. I have it on the sand bed about 25" from a 150watt MH in a 28 gallon EcoSystem. Should I move it up. My bulb is a 14K that is about 7 months old. Should I move it up are just let it be?

Well actually the question is more about just one chalice.....

I would move it up higher. 25" on a 150w is probably pretty low par -

We keep ours a little less than halfway up on a 27" tall tank with 3 400W Radiums. It has maintained its blue color.

I would say move it as well. Mine are no more than 18 inches from my 250's 20K's. Some are alittle closer but 18 inches is the farthest (hope thats spelled right)
