This 'stuff' has started to spread over my live rock over the past few weeks, at first I thought it was good and due to the growth enhancer I use for the LR & LS, but now I'm not sure! Please help me ID this...thanks!!!

Another pic of the stuff....

Does it look like a sprout or a bubble?

 

[vickicj]

Definitely not a sprout, it's very smooth and even, no spores or sprouts coming off it....

 

[bigarn]

Can you circle it in the pictures? If you touch it does it feel hard?

 

[vickicj]

I just went and touched it and although it appears like it would be hard, it's not at all! I was able to pull off an entire piece of it in one slimey piece....sorry the pic isn't clear but I minimized it as much as possible, hopefully you'll be able to see what it is....

 

[bigarn]

It's definitely some kind of algae, but sorry I can't tell from pic.
You sure it's not bubble algae?

 

[vickicj]

OK, hopefully this pic will be clearer, here goes!

 

[vickicj]

Guess that file was too big, trying again.....

 

[vickicj]

By the way, I don't know what bubble algae is...do you know of anyplace that has pictures of different kinds of algae? I've googled a search on marine algae and lots of info comes up but no pics...by the way, thank you for helping me out with this!

WOW!...LEAVE THE HOUSE NOW!.....lol Now I see what you're referring to. The only thing I can offer is guesses..a large Sponge, or a monster case of Cyano. Do a search for both and let me know how you make out.

Cyanobacter. It's usually a sign of excess nutrients. My guess is that you're right about it resulting from your Growth Enhancer. I'd suggest not using anymore of it.

It's hard to tell, but in the left side of your first picture, it looks like you have aptaisia

 

[vickicj]

Thanks!!! I was able to grab one and pulled the entire piece off, should I go ahead and get it all out that way? I will definitely stop using the enhancer too...just tested the water parameters, here's what I have:
Salinity 1.024
PH 8.0
Alkalinity 4
Nitrite 0
Nitrates 10
Ammonia 0

Darknes, I think you're seeing my curly q anemone...

 

[bigarn]

Definitely...if you can get it all out, do it.
Do 10% weekly water changes with RO/DI water only.
It's Cyano bacteria as I guessed and Bang Guy clarified.

 

[vickicj]

Thank you everyone!!! I'll definitely do all that was suggested....and I really appreciate your help!
