I have a dark maroon/purple alge growing on my sand bed in the display tank. It is forming into a hair type formation. I cleaned it all up last night and it was back today when I got off work. It is not the same color as the outbreak of coraline alge that I have seen in my tank in the past weeks. It is a harder purple. More of a maroon or red purple. Is this something I should worry about or no? I just added 9# of new synthetic sand to my sump, from a dry plastic bag that I bought at LFS. Could this be the reason for this outbreak of hair type alge? Should I act on this?
