Does it look hard like a shell or soft looking? Your pictures aren't showing up.

It could be coraline, or it also could be cyanobacteria for instance.

what bean said. pictures aren't showing up.

if you can easily rub it off with your fingertip, it's cyano, if it's hard and on the rock, it's coraline

what both above have said..and if it's soft and mushy and smells like rotten peanuts, you better shut down your tank and quickly put on a hazmat suit.

What's your po4 level at. Its probably cyano. No big deal we all deal with it at some point

 

[oredith]

sounds like your tank is still cycling anyways. it should go away on its own in due time.

What are you testing with? How's your flow? What lights are you running?

I test with aqua redlab from uk. My flow was low for only 2 days cuz I don't have any extra water to add it was low level in the sump so I decrease the flow for 2 days and now I open the valve to 90%. my lighting is led blue stripe and white 9 hours on.
