Red Mangroves Die'n?

I have 2 Red Mangroves that I think are die'n, How can you tell if they are?

 

The outside of the pod will get black and woody. Kind of look like a ripe avacado.

 

Yeah I think mines are die'n, When I got them one of them was sprouting a leaf now it's turning black. Both of them are turning like brownish/blackish, What should I do? Or what can I do?

 

yeah, they sound dead to me, not sure there is anything more you can do for them, maybe john from reefcleaners will see this and have an idea.

 

I've never been able to turn them around once they get that way. But like telgar mentioned maybe John will know what to do. You could email or pm him if you don't want to wait.

 

I got them from John, They where healthy when I got them. Could it be because I have no nitrates or phosphate?

 

hard to say, I got 6 from john and had 1 do what your is doing, the other 5 are growing great, in fact I may have to prune them soon

 

Nice, Mines are only blackish at the top. The rest is green, And they have roots :-/

 

I got mine from john too and most of mine were black on top. 2 of them were really bad, the others ( I got about 6 of them too) were ok and only 1 is doing good. But I got them that way.

 

all but two of mine went the same way. I dont know about seed pods living really well, next time i grab up some mangroves i am gonna get them rooted and leaved sp? anyways i want to hear what people have to say about this
