CORAL HELP PLEASE
 

I have a Merulina Coral that I've had for a year. It's always shown great color

The last month it's browned out and polyps have been out quite a bit. Which is strange since its never shown much polyp extension before.
Water perameters are good nothing changed. I run prodibio and carbon and rowa.
I know it a more difficult piece to care for so looking for advise

Also it's under a brand new geissmenn 250 watt 21k halide

Ouch buddy I feel your pain I had a colony that was massive did well for 1 1/2 yrs then browned out, then slowly died.showed growth forever and then died off, I ended up fragging it and giving it away, was nice tough never did figure out why I guess its just one of those things .

Has your collection of corals grown substantially? Maybe your elements are being used up quicker than your used to. Just a thought.

I've been reading and it seems that some
People have had success in lower light while others in high light also doing well.
I've moved it to a low spot with nice Flo. I'll just have to watch
It's not receding at all looks healthy just color

Yes Jason there is Alot in the tank and I also thought trace elements could be low.

Maybe your bulbs need replacement.

Bulbs are 3 weeks old.

Has it been through a light change before?

haha. i was thinkin that when i wrote the age of the bulbs

how old were the bulbs before you replaced them?
