Live Rock ID please!

[blueangelc]

I 've recently had this Live Rock and it is currently being cured in my QT. However I have just noticed this white (web like) substance spreading across the live rock in the last few days. Does anyone know what this is and is it harmful to my fish tank? :thinking:
Any suggesstion?
Thanks,

You have a poisonous sea spider in your rock. You should send it to me.
seriously, I had this in the beginning of curing some of my live rock.....never did figure out what it was and it went away never to be seen again.

My guess would be a bacteria colony. Are you letting your ammonia get too high?

 

[darth tang]

That would explain my experience...My ammonia hit 5.....I was gone for a couple days. Thanks Bang.

Thanks Bang... How would I get rid of it? Is it just a matter of changing my water? If it is something harmful, I don't want to put the rock back in my tank... Thx.

Mine went away after the cycle. So changine the water out to lower the ammonia should take care of it and it will dissappear...if it is the ammonia.

Thanks Darth. Do you think I have poisonous sea spider? What does it look like. How do I get rid of it?

He was kidding about that.

You kinda gotta get used to it with Darth. Yes, do water changes and siphon it off the rock. It is just telling you the rock is curing...dont worry.
