you runnin that light full blast?.....could be tip burn from the light.......alk is a titch low, but not obscene.....

[the marine apprentice]

looks like your burning the tips off derek. just like doug said

Looks like algae to me. More flow and less nutrients needed.

Should I move it lower in the tank....I have flow hitting it hard cause thats what i thought, but seems to be getting worse...

It should be getting indirect flow. Its possible that the flow is taking the tissue right off the tips if its right in front of a powerhead. Maybe move it a bit lower and out of the path of direct flow. It doesn't need a ton of flow, just moderate.

i'm leaning more towards tip burn as well. is it only this colony or are others showing the same signs? was this colony new to the tank?

i would raise your light a bit if you can

I am with Lance on this one a few of the tips look like there is some algae on them.

So if it is algae do I scrub it off? Because my other coral is fine.
