Mermaid's wine glass. It's a good thing-IMO.

I guess you can get rid of it by giving it away.....not a bad position to be in

yellow tang maybe

It's a good thing to have in your tank.....but if ya do wanna get rid of it......I'll take some......

I had some growing in my 29 last week. Didn't know what it was so I pulled it out. Only a small area about 3 inches or so. Why is it good? Is it fish food for tangs or just nitrate export? Does it get out of hand?
I'm glad to have a name for it now.

I would have voted for Caulerpa nummularia. If that's what it is, get rid of it. Caused me many problems in my previous 39g tank. Evil stuff.

Any macroalgae can become a nuisance if your nutrients (nitrate/phosphate) are not held in check. Blaming the algae for growing out of control under such conditions is avoiding the root cause, IMO.

I would suggest that you review your feeding/nutrient additions (amino acids?), and/or implement more advanced nutrient control measures. These may include denitrification reactors, carbon dosing, algae scrubbers (see Acroholics thread) or plain old water changes, to name a few. JMHO

Can't disagree there. With that said though, I found nummularia very efficient at nutrient uptake in my old tank and difficult to control. My cheato croaked long before the nummularia showed any signs of stress.

Interesting, thanks!

In Dave's (Acroholics) thread about algae scrubbers, he references that 'turf' type algae are among the most efficient* nutrient processors and therefore out-compete other algae types-FWIW.

*(I suspect/conjecture this is due to a very high surface to volume ratio. These algae are very small)

Thanks to everybody for their input. Since I don't have an algae lover tang I will try to remove or keep under control.
