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

The stuff can actually be peeled off quite easily. A matter of fact if I create a strong wave like motion with my hands over it, the stuff peels right off and by the next day, it grows back in the same place. I've adjusted the water flow to pass over the rock in short intervals but this seems to make the mushrooms quite unhappy. I'm feeling very positive about the source of this particular rock. It seems to be made up of some product that may have leeching phosphates.

Hey Tangster, The rocks was allowed to sit in a new batch of saltwater mix, not freshwater. (Oops, my wording may have misguided everyone)
