Cyano or Coraline?

BL1

.............
I'm starting to get some color on my rocks but, looking at pictures I can't tell a difference between the two. Can you you tell me what it is on the rocks?

Sweet, thanks guys. How can you tell the difference between the two? I hate being so new, I'm worrying about every little thing lol
 
The easiest way is to take a turkey baster and blast the algae with it.If its cyano,it'll come loose.
Just wait till you've had that tank a couple of years.You'll know when your about to have an algae outbreak just by the color of the water in your tank.:mrgreen:

Is it normal for that stuff to grow on snail shells? I just noticed one of my snails is covered in it.

yep they will turn purple too...as well as your glass, powerheads, filters, sump...about anything thats got a surface in the water can get coralline on it.

Cool, he looks pretty BA with the coraline on him (I think all the other snails are avoiding him now). I can see a few spots of it on the back of my tank too already.
