What is this green algae?

pwilliaml · Jun 10, 2018

I'm not sure if this is bryopsis, green hair algae, or some other kind of green turf algae. It's slowly taking over my tank no matter how much I peal off. I've tried, snails, urchins, crabs, hair algae, fluco treatment. I have a algae scrubber running growing nicely and a giant skimmer. Nitrates are between 3 and 5 ppm and phosphates are right around 0.03 or lower. Any help is appreciated. It would be nice to at least know what it is, and even better how to eradicate it. Thanks all.

Hair algae. A couple critters eat it but not reliably from what I hear. I've had luck with vibrant, and others swear by fluconazole but I can't get it in Alaska so I've not tried

I have something very similar in my mantis tank. If I put some in my reef tank the tangs go to town on it and it’s gone in a few minutes. They share a sump so same system. Turbo ats is growing like crazy, just nothing to eat it in the mantis tank since he’s such a murderous *******. (My last mantis wasn’t quite so murdery so I was able to keep a tang or two in there with it.)

I just took a ton of it out manually. Seems to be the best way to deal with it. My tuxedo urchin is more interested in coraline and it like to use the gha as camouflage.
