cool I bought this from a LFS
established tank that had no sign of coraline algae for 4.99 a pound. Dont most places sell rock with Coraline algae on them for $10+ a pound? Ill have to go back and get some more :p
also this rock had no color to it when I bought it and it is sitting in my cycling tank, is this normal to be growing this type of algae before the tank is even cycled?
