Good, Bad, or Just Ugly?

I'm new to saltwater aquariums. I'm having an dark algae problem. What is it? Should I be concerned? How do I get rid of it?

 

Holy WT?

 

Wow! those pics didn't post right at all!!! See these attachments.

 

That's better, kind of. That's not algae. That's cyano bacteria. Not good too much bad stuff in the water. What is your livestock, how much do you feed, how often do you do water changes, what are your paramiters?

 

Oh and welcome

 

Looks like its taking over your tank pretty much sorry to see can it be picked up/Off without breaking up? or is it slimy like Cayano?

It's ugly, redslime algae, your water must be high in phosphates and nitrates, siphon it out, you will need to do a water change anyways and get a skimmer, but don't listen to me, i'm just a rookie :/

 

I had a similar experience and one of my six bulbs were out have you checked your light bulbs?

my fist plan of attack as well... 7 fish in a 29 ga? I have seven fish in a 90ga? possible culprit over feeding!

Something tells me that this is when you use tap water... what kind of water are you using for top off as well as starting the tank? RODI? or tap?
