Purple/red algea

[asylumdown]

Slimy sounds like cyano, but honestly that pic just doesn't look like it. The only thing in that image that looks 'cyano-ey' are those solid dark red/wine coloured patches, but they seem to have hard edges where the more lilac coloured coraline is growing in them. Cyano mats don't usually look like that, they'd smother right over top of everything on the rock and wouldn't leave such neat boundaries between them and the other things growing there. Though the colour and texture is very much like cyano, so maybe it's just a young patch?

Is the chemiclean having any sort of an effect?
