Invasive macroalgae

[Furred Feathered & Finned]

One of the first things I bought for my newbie reef tank was a rock with several mushrooms. It had a tiny piece of this attached. Now it's trying to take over my tank. It's a constant battle to keep it removed and it clings to everything. I am setting up a new tank with a sump and

refugium, which this basic tank doesn't have. Should I just scrap the old rock and let it die, or will this get under control once I can manage nitrates and phosphates better?

I managed to get rid of it by constantly removing some and keeping a patch of it closer to the light, a kind of algae refugium.
A tang could help too if you have a sufficient sized tank.
And peroxyde works well too, else dip the whole rock or use a syringe

or an urchin

Just manually remove it in big clumps , its a great one to have once you do setup the fuge , prolifera caluerpa

Will the peroxide kill the beneficial bacteria or Coraline? I managed to clean one rock with aggressive use of a plastic brush....

Looks like Caulerpa prolifera to me. I wouldn’t use any type of additive, just manually remove large chunks and try to get some inverts that will eat it.

A naso tang almost certainly will eat that, maybe a rabbitfish too. Not sure how big the tank is. Small Naso's are pretty easy to come by but also unfortunately more fragile then the older ones. I did beat a similar macro with a Naso in the past.

I'm currently trying vibrant to kill another invasive marco after the rabbitfish I added only controls but not eliminates the problem. Too early for me to tell if it's going to work or not but there are so many good things said about the product I have high hopes that it will work out.

in my experience zoas and GSP are barely affected from being dipped into peroxyde , I don't know about stony corals though

Hmmm. I'm definitely a newb when it comes to this, but I thought bryopsis was more feathery?

 

[Topekoms]

That is not bryopsis. It is def Caulerpa what size tank are you upgrading to?

 

[anon9896]

I second that, it's a type of caulerpa.
Know this, when you tear some, if little pieces floats away they WILL regrow so you better be meticulous.
It's not the hardest one to 'remove' luckyly for you.
Another trick, if you let them gros in a thick and compact manner , the bottom part tends to be easyer to seperate from the rock.

This is great as a refugium macro but it is aggressive, tangs and fox faces love it.
As above, manual removal and grab it as low to the rock as you can.

 

[najer]

This is prolifera in my little tank, long blades.

 

[Super Fly]

tangs and fox faces love it.

Agree, my foxface loves it whereas my tomini tang not so much.

 

[Silent]

That is great for a fuge. Actually hard to find from vendors now a days because it is so invasive.

I stand corrected, it looked much different on my phone. I thought I saw the bryopsis filaments in the smaller picture.

 

[Tamberav]

You could put the entire rock in your fuge, it's a great macro for that. I bet it has been helping you all along.
