Hi Tangster, I'm a little confused with your response. Can you repost it? The cyno bacteria shows up more on the picture to the right side than it does on the left side. This happens every time the intensity of the lights are at maximum. At low light levels the red slime on the picture to the right hand side disappears. I am suspecting that it could be some nutrients coming from the rock. The rock seems to be one of those man-made type that may have been created for frags. I'm not positive about this but it seems a bit too light in weight.

Maybe it is saturated with PO4s ad the stuff you are seeing a algae of some type but not cyano as light has no effect on true cyano's ...Its bacteria not an algae |
