Hey guys and gals, I've had my 75g for 2 years and do monthly water changes. With in the last two to three weeks my trech brain coral, which is typically greatly enlarged, has been shriveled and has lost a lot of its call. I have had the same lights for over a year (LEDs) so I know it's not that.
My parameters are good:
Calc 390 (little low)
Does anyone have any idea what might be going on? I've had this coral for years with no problems even when the tank parameters were off.
