What would make a chalice brown out?

Hey all you chalice experts out there. I have a question for you. What makes a chalice brown out? All of my parameters seem to be in check. Alk=8 to 9. I need to measure my phosphates. Calcium is 350. Magnesium is 1500. I have a newer My Miami frag that is very brown other then the huge orange eye. I also have a ECC Hybrid chalice that is a very light brown in small areas. So what do you think could be browning out my 2 chalices? All of my SPS look sweet. Thanks in advance.

what lighting do you have? Chalices dont need a lot of light (im guessing you have a lot of light if all your sps corals are doing great). Good Luck!

Thanks. My lighting is a Geismann fixture with two 250w Radiums and 4 54w Blue+ T5's. I am also going to add 12 Cree LED's to the fixture. So maybe to much light then?

Yuuuuup! That's your problem. Put them under shade at bottom of tank

Thanks guys. I will be moving the chalices in a few minutes.

Not sure what the deal is, but my new chalices almost always brown out or loose their colors when I introduce them. Seems to take mine a couple of months to get their color back. And I have a couple that suprisingly enjoy more light. So I would start them low, and move them up if they don't color up. I have several chalices around 1/2 way up my rockwork under 400 MH. They are not directly under the light getting blasted, but not on the bottom.... Good luck, those are nice chalices
