Can you Post a pic. And describe what you mean by coming off. Like detaching from the stalk? Looks like its melting? Or dying? Corroiding off?

That's a lot of flow for that size tank. Duncan's do best in low to intermittent med flow.

It is.... But usually with that's not going to cause them to come off their stalk. It would just make mine close up for a couple of days. Have you tested your water parameters

I recently put some gfo in a small filter bag in the filter

I agree with NanaReefer, I only have a 240gph blowing at my duncans. I would test the water and turn off a powerhead for awhile just to see what happens

I have 2 large duncan colonies and one is in a area that recieves constant flow a foot away from an vortech mp40. I keep looking for him to have a problem but its been months and months and he seems to be fine so I have left him there. just my experience.

i concure way to much flo beating them apart

 

[josh88]

Wow guess i learned something new. To much flow on duncans makes their heads pop off.

What's your chemistry measurements? And would you post some pictures please.

hi any update?
flesh wont come off just like that on lps with too much flow...is there any brown slime/receding?or whole flesh just came off?if its the latter then i think whats happening to your duncans is that the flesh are bailing out...
if u can post some pics so we can see whats happening will help a lot...
also can u give us your water parameters?
lps are prone to polyp bail out....i have experienced this myself but that was when my water chemistry was off...
try to do some water change for now and put some carbon....try to put it somewhere where theres less flow and see what happens...
