Hello people. I am having a problem with red algae. It's growing on the sand, rocks, walls, and there were even random strands of algae floating around on the surface a couple days ago! (I removed them) I am mainly concerned about the sand bed. The rocks are fine as long as the algae don't grow out of control on them. The algae seem to like the white/red lights the best. I know this because whenever I have the blue light on, they don't grow. I can't leave the white/red lights off because my candy cane coral shrivels up whenever I turn 'em off. Nitrates are below 5 and have been so since the tank was set up. I run the Coralife Marine Filter with Protein Skimmer. I use LEDs for lighting. Can someone please tell me what kind of algae this is and how to get rid of it????
