These are about a week old, but the leaves are turning brown and the stalks are getting thin.

They're in my quarantine tank with 2 x 200W CFLs

my reef tank is pretty healthy.. good coral and fish health...

They need nutrients to thrive, they need nitrates and phosphates. If your tank water is too clean, that might be the problem. Also they like humid air. Mines were seedlings 2 months ago but now they are growing multi tiers of leaves, I feed once a day, I have 5 fish, and it looks like my bioload produces enough nutrients for my mangroves to thrive.

I have a ATS and it generates massive hair algae do my water has plenty of nutrients
I also have a Xenia scrubber and chaeto box
All good except for mangroves

But the mangrove deterioration is rapid :(
Here they are a week ago

Were they kept dry or in freshwater before you bought them? If they were kept in fresh water or even brackish, they need to be acclimated to saltwater over a long period of time. Probably several days. I've never had luck keeping mangroves that people propagated in freshwater.

That scrubber is staving them. Just shows how efficient they are. I planted mine in clay pots filled with live sand and it seemed to help. also make sure you mist them with fresh water once a week.

I'm not misting at all. Could that be it?

would have to agree that the scrubber is probably out competing for the available nutrients.

I just found the salt spray builds up and the tips burn. figure mangroves in nature receive rain. Hope this helps, I sure have learned a lot from your posts.

getting worse day by day... not enough light?

I sprayed with fresh water

And I have to say they came in very healthy

I have mine directly under HQI 14000K Phoenix bulbs. They do seem to stretch to the light. My scrubber is still maturing so wonder if I'll have issues with them in the future? but I don't think that is your issue considering they have been in the tank only a week or so. Might do some research and see if you can cut them back and start over. I think maybe the poster who mentioned they could have been grown in fresh or brackish water might of been right. I'd ask for a refund! They sure went down hill fast.

should I put them back in freshwater? Is it too late?

Fourstars

Might be worth a try. The tops that are all brown you could try cutting were its still green and see what happens?

karimwassef

how far do I cut them back? the brown stems are drying up, do i cut back to the green base?

Fourstars

I think if you cut at the thickest part it wil die. I'm thinking maybe an inch up from transition?

I see you mentioned you sprayed them with freshwater, I'm pretty sure this needs to be done daily, esp the undersides of the leaves if memory serves me right.
It sounds like you have a ton of nutrient export going on in your system, not sure if lack of nutrients could be the issue or not. Lighting wise I know mangroves have a very high tolerance, but possibleven to shock via going from dimly lit to intense light? Just throwing out ideas.
Did LA specify if it was a white, black or red mangrove?

I have one mangrove in my refugium and it's doing well for several months.
It primarily gets ambient light and so far I have never sprayed it with freshwater. It took a long time to get going with sprouting new leaves, but started growing roots pretty quickly. Another batch I got from another LFS isn't doing well at all.
If you have the chance to pick them out yourself at a store, pick the ones that have fresh roots over those with many leaves but no or only old roots.

I'm going to try a transplant into fresh water with miracle grow in a sandy soil.

I hate giving up on them in my reef, but I need to do what's best for them.

Mangroves will never thrive if they are not grown in substrate. They will not grow root hairs which they absorb nutrients with, they will only develop thick structural roots. Unfortunately Anthony Calfo's article has misled many people to think that this is a good way to grow them and it absolutely is not. Also, rapid shifts in salinity will cause osmotic shock and can kill mangroves rapidly.

Ok. So is it too late to put them in sand now?

I would do still do it, they might still have a shot.

I think your problem may be that they had already sprouted when you bought them. I've had good luck with unsprouted pods and once they sprout leaves/roots it's best to leave them alone.

I had one that was doing well for a while with several leaves and was attached to a rock. Once I moved it to another tank it gradually dried up and died.

The ones I have now I planted them where I wanted them and mist then every couple of days and have been training them with wire and trimming new growth. I've been doing this for a couple of years and haven't killed them yet.
