Probably a sponge, or could be cyano. I'll check back for pics.

 

[jef9891]

Sorry Its not a very good pic.

Did it come in on a new rock? Can't see it very well. Looks like cyano as far as I can tell.

 

[jef9891]

it just showed up. the rock has been in there for maybe 3 weeks.

 

[jef9891]

Heres a better pic. Trying to get the best pic i can with my phone

 

[NathanMI]

Looks like cyano.

The test i have is for PH, Ammonia, rite and rate. which are 8.1,0,0,0. its looks like that blue green cyano but doesn't look slimy. if it is that i guess im screwed.

 

[NathanMI]

Is it a new tank? It seems like its cycling with all that ammonia.

 

[jef9891]

it is a new tank but there is no ammonia. Ph is 8.1 the other 3 are at 0

 

[jef9891]

well the tank has been running for about a month and half

 

[NathanMI]

Oh, I get it. I had cyano in my 90g I just set back up and I added a power head and it went away.

 

[jef9891]

well it has a power head pretty much right on where it is. and theres enough flow in there. have a hydor 750 and 1400 . it the black stuff is almost right in front of the 1400. so idk

Looks like just dark purple coraline to me. If it's the patch in the center of the pic.

 

[jef9891]

Yes its the dark stuff right in the middle

 

[salt_for_brains]

Can you tell if is hard or if it has movement from the flow of the power head? If it is hard it could very well be coraline.

 

[jef9891]

I seems to move with the flow but the hair looking stuff is really short. It had other stuff growing through it. Stuff that is everywhere on the rock. Plus i noticed some white shell looking things under the rock and i know those things are hard.
