Hey I have noticed I have a few colors of algae in my tank on my rocks, a lot is purple and I notice that I am beginning to see yellow color, I am not sure if its algae it looks like fur, its not super heavy but just one one of the live rocks, also I noticed a blue in color fur size of a pea? I am curious what all this could be? or is this any problems? let me know what you guys think.. thank you

As your live rock matures you will see various color changes and algaes grow. Eventually these will all be replaced by a nice growth of coraline algae. I find that maintaining the correct calcium and alkalinity levels from day one is beneficial to encouraging the onset of coraline. I dose calcium even prior to livestock... although not as much is needed, obviously.

LOL, yes I guess I did know that. You can't imagine how many people send private messages every day about their tank. Sorry, it is hard to keep up with the details.

I never really gave it much thought as to the exact types of other algae that show up on the rock. I can't even recall this discussion before. OF2F.... thoughts?
