I'm in the process of putting 30 lbs of cured LR into my display. I started to look at the rock and found some spots with some yellowish slimy algae. What is this? I've googled and read about yellow/mustard algae in swimming pools. Is this the same stuff?
Should I scrub it off?
Please respond asap!
Thanks

And I'm finding a bit of this green grass-like algae. it is brittle and hard to get off. Is it something that needs to come off?

First one does look like a sponge.
Second one....Well I feel for you...You will never ever get it out of that rock... If it is what I have I finally banished it to my refugium after 5 or 6 years of trying everything. I've scraped it, burned it and anything else I could think of. Possibley some form of byropsis

So the sponge can stay?
And the yellow algae?
But i should try to get rid of the green brittle stuff if possible?
??

Well the sponge would be fine. Since you have it out of water odds are it will die. The yellow stuff looks like die offf. I would leave that rock in a bucket with saltwater and a light and see if it changes. Odds are it will just disappear from die off. I don't think the grass stuff is a form of byropsis. It might be but the figi I bought had stuff like that on it and it just died over time. Good luck you never really know what you are going to get from live rock.

i had some of the green grass looking stuff on some LR from the lfs, my tangs chomped it up and its all gone now.
It didnt hurt anything in my tank just ended up as tang food!

Great! Sounds good. I'm just glad it doesn't sound like I'll have to discard the rock. I just didn't want to add anything that would be a problem in the future.
The yellow stuff scrubbed off just fine with a toothbrush. The green just isn't coming off, so I'll see how it does in the tank. I looked at a few sites about byroposis and I'm pretty sure it's not that. It is much smaller than the photo looks. The photo is real close up and cropped. Well, we'll see how it goes!! Can't wait to have it covered with coral!!

Good luck with the green stuff, I have a zebrasoma desjardinii tang and even he would not eat it, nothing would.
