Chaetomorpha?

[Jayson Ledbetter]

i purchased some chaetomorpha today for my refugium, what is this that came with it?

I would think it's the balls off of some grape caulerpa. I would take it out until somebody more positive can ID it and leave it in a cup of tank water for now in case its something bad.

That's green bubble algae. Remove it without piercing any bubble. Then research it. In that order.

It's definitely not green bubble algae.

I would get it out of your system if you think it's. grape Caulerpa. I had it go a sexual on me and it is a pain to get ride of after that.

I didn't see any stalks/vines definitely grapes. It's not a lot to do any harm. I'd keep it. Some fear of it going sexual.

I took another look at your pic and I see some green balls on the glass bottom. Are there vines that the grapes are attached to?

Looks like a bunch of gapes, but don't see any vine

Will probably die anyway.

Grape Caulerpa has vines.

I had a tank get wiped out by Caulerpa (grape and feather) breaking down and releasing spores. If you keep it trimmed that may not happen, but I will never willingly add Caulerpa to a reef tank of mine. Chaeto and dragon's breath both work well without that problem.

Alternatively, it's Valonia that looks weird, and you should remove it as well.
