    Hey there guys,
    Was just checking out my tank and noticed a couple of purple spots on my rock.
    Is this anything to be worried about?

    A picture would deffinetly help, once I saw purple spots on a piece of wood I had in my 55G convict tank I took it out just to be safe.

    I did not think you could get cyno in freshwater. I know all about cyno. I am a convert from salt to fresh. Cyno is caused by to many phosphates.

    Yeah, cyanobacteria and some red algae (black brush algae) have fresh and saltwater forms. I guess their adaptations is what made them some of the harder forms of algae to remove once they get going.
