An algae bloom..

It also looks to me you have a little bit of red slime algae (cyano). Hard to tell, or is that all coralline algae?
 
On which picture? If its the third one you are talking about, I don't know what that is. I don't think its coraline becuase its like a plate and hanging off the rock. I broke some off before and it was floating around the tank.
 
Here is an update. The algae has significantly decreased and has almost disappeared. However, most of it has visibly disappeared, and it surely doesn't mean it won't be back. Since i am more aware, I will clean up any aglae that starts to grow again. Some red bubble algae is still around, need to syphon that out. My clean-up crew has done a good job, one of the crabs did not make it but everyone else is doing good. My emerald crab literally cleaned all of the green hair algae off my one individual rock, was happy about that, but too bad I won't trust him when my reef comes. Sand looks a litter better, I netted out a bunch of clumps of dirt and such out, while keeping a lot of the aragonite still in the tank. Probably messed up the bacteria growing in the sand a little, but not a whole lot to really harm it.
 
I have 2 emerald crabs in my 55g reef tank, and they are great guys. They NEVER stop eating. And I have never had any problems with them going after live stock, but they are only a little smaller then a quarter right now. they are fearless, and do not even budge when the fish snoop around them, but they eat like made men, staved for weeks.
 
The one I have now is pretty small too, a little smaller than a quarter. He only has one claw atm too. Surprised he ate so much, just wish he would help me go after the bubble algae!
 
I've kept my tank @ 78 degrees and did a SIGNIFICANT water change and vaccumed the sand...no more hair algae.

I think, for me, it was the stupid crushed coral stuff couples with some long ago over feeding plus 86 degrees for a week that caused my algae....lol...

Have to air condition the whole house to keep my tank cool...grin
 
Yeah Sub, my CC is the reason my algae is ding so well. I think when I inherited the tank 6 weeks ago, we stirred up alot of stuff that was buried in the bottom of the CC, and it caused a huge algae bloom, brown, red cyano and green.

Super, my EC's do not go near my bubble algae either. But bubble is so easy to remove, I do not worry.
 
Im going to do a water change and clean everything up. I got carbon running in there too, I should be ok. Thanks all!
