what is this? It is in the chaeto that I just bought.
It looks like some type of Caulerpa.
looks like a type of caulerpa. if you dont want it to grow in your sump remove it
Is it safe?
I have some in my sump doesn't seem to get outta control.
It's a macroalgae type. I do believe they go sexual, but if that's all you've found, I personally see no problem keeping it in your sump.
it is safe until it decides to spawn or "go sexual" which will result in a tank crash. I personally removed all of it from my sump due to this risk.
I agree - I've had Caulerpa go sexual and wipe my reef. Having said that, I didn't keep it pruned (and other reefers who do prune it don't have problems). It does grow quite rapidly, but I don't see a good reason to use it over chaeto. I would be curious what their relative growth rates are . . . and also for gracilaria, ulva, and dragon's breath as well!
Sorry ....my fuge runs 24/7 because I have species of caulpera..should have mentioned that..
Really? Everyone is saying it's Caulerpa I thought it was Bryopsis. I had a bunch of the same looking stuff on my chaeto and i cut down my chaeto and kept the clean parts, but i thought it was bryopsis. If it really is Caulerpa then that may be a different story.
Edit: yea the more i look at it the more it looks like Caulerpa
Too thick for bryopsis...would be thinner more wirish and won't grow nearly as tall.
