Purple Carpet/Blanket type Mossy Growth ??

[chachi]

Hi All ~
Over the last few months my tank has begun to get a purple carpet/blanket type mossy growth growing on the LR and in the sand. I remove it during water changes but it grows back within a week. Same thing with a green fuzzy moss type growth on the LR.
Any suggestions or comments are greatly appreciated. Even it is not harmful I am curious to know what it is -I've spent the last hour searching the board with no luck.

cyanobacteria AKA redslime algae (even though its a bacteria) sounds like hair algae underneath it. try looking that up, maybe you'll have some luck.
