View Full Version : What is this?

10/17/2017, 05:22 PM
I recently relocated my tank to a new home. After doing so these green things have showed up everywhere? They almost look like featherdusters but certainly aren't. They seem to be spreading at a pretty rapid rate. Any idea what they are and how to get rid of them?

Your image isn't showing up. Photobucket no longer allows image sharing on forums unless you pay for one of their premium services.

Yes, it's been awhile since I posted photos on the forum, is there a comparable service to photobucket that is free?

It's showing up now as the attachment. That's a calcerous algae, I've forgotten the name. I've had it before, but never as prolific as you seem to have it.

Any idea of what gets rid of it? Had a buddy who thought tangs would take care of it, put two in and they haven't touched it yet (only been a few days).

Anyone have these and know of a reef safe predator?

Looks like Codium algae and it is calcareous algae. I don’t think you will find fish that eat it. It’s actually not a bad algae to have though it will consume calcium. Best bet is to pick it out if you don’t want it. Raising alk may kill it too.

I never tried to remove it because I liked it, but I never had it as prolific as you seem to. 8 would just try to crush it with a siphon tube and suck the bits out during water changes. It's rare to find livestock that will touch calcerous algae. Maybe an urchin, but they will decimate your coralline too.

Neomeris annulata.

beat me..

It seems to really love stronger light towards the "red" side of the spectrum..
If you can reduce the amount of red spectrum in your light it will go away or get more controllable..
Which from the picture your lighting seems to have quite a bit of red spectrum..

Go more "blue" or really less "red" if you can..
