How do I get rid of this stuff. I had used red slime remover before and it worked in taking it off my rock, but now I have this patch of stuff on my sand. I have switched off my lights for a couple of days and the stuff disappears until the lights are on for a few hours. I have somewhat heard of people flipping their sand bed to combat algae. I know cyano is not algae but will it have the same effect? Any help would be great. I have a 1" sand bed. So I am not worried of any release of bad gasses.
