Ok so I'm pretty sure I've got a GOOD amount of green coraline (it's not easy to scrape off, pretty sure it's coraline) growing on my rocks.... the purple doesn't seem to be spreading at all...... what causes the different colors??? Is it the lighting??? I'm running 4x65pc 10000k and actinics 12 hours a day......
I'd just like to have a little more purple and don't know what to do.....
