It means she bumped (same as replying) your post back up to the top of the list so hopefully someone can answer your question. :)
 
Looks like something you may want to put in a quarantine tank and see what it does under 6500k light. If it ends up going nuts, it could be an invasive type that ends up smothering your rocks. I havent seen anything like that here, but I know when i do find new things, I like to separate it and learn about it before I let it be a full time member if my display tank.

Precautions are always best when it comes to things you dont know about in any case. Now if it seems like a Manageable algae in quarantine, its up to you if you want it in your tank,

It does look pretty cool though, I wonder what it tastes like? Do you have any herbivores? Do the snails/urchins/crabs mess with it?
 
My astrea snails are snacking on it pretty heavily. What you see in the pic is some strands they missed. I do have a QT set up for when I start getting fish, if I put this stuff in there, will it interfere with QTing my fish?
 
That all depends on what you are doing during quarantine.

Medication/ hyposalinity will effect it, and if you do not keep it under at least a plant rated bulb it will also dither away. Best bet as far as long rune simplicity would be just to have a tank JUST for the algae in case your fish need treatment. Unless you know for a fact that the fish you plan to quarantine are NOT ILL...(aka not from a store unless they also quarantine EVERY FISH THEY GET...unlikely since they are a business). I would actually try to email a marine biologist, or facility the pictures of the algae for ID and info. Who knows, maybe you found a freak strain that can cure gambling addiction? My guess is that it is not something aesthetically pleasing (in comparison to corals) and can take over given the right situation.

I guess I should ask...do you want to keep it? IF so, here are some cool things algae can do.

1)oxygenate-any time there are plants, o2 is being created and waste is being consumed by the plant.
2)diversify ecosystem- The algae when grown out can house thousands of different pods and critters. Ever go fishing and pull the weeds off your lure?? YUM!!! Full of bugs!
3)shelters prey-baby fish, larvae, and anything else really can hide in it

do some experiments. See how the algae does when kept moist in open air, maybe this algae could be utilized in an ALGAE TURF SCRUBBER? I love those things, I used one for months before i got a bigger tank.

Everything in the ocean has a reason, and if you can find what this algae is capable of, it could be very beneficial...at the same time it could be a mutated strain caused by accidentally dropping uranium in your tank. lol, so yea

Try this place, im not sure how credited they are, but i just gooogled ask a marine biologist. MESA - Ask A Marine Biologist
 
Agreed. Unless the cuc does keep it in check...then its just another food source. Infact, my tank has so little algae now that the urchins have started eating coraline. I wish i could get some hair algae to keep the purple on the rock.
