My holly grail and gold torches slowly loosing color.

[andre zaharchenya]

what could cause this torches to loose color? Other euphilia and green torches are looking good except the expensive torches. I dose kalkwasser, Red Sea coral colors and Fuel. Slowly transferring from RO to RO/DI.

Corals will change colors to environment. Some just do not maintain color in some systems. I have done experiments with many sps from my system to another reef keeper just to see the color differences. Interesting. Never a torch, but I have some that change colors from what you see online or in another tank.

Lots of things impact color, including lighting, nutrient levels, and possibly trace elements or lack thereof.
