Fellow reefers, Iv been dealing with a mild case of red slime bacteria for about a month now with little success. I have reduced light cycle to 8 hours, cut back on feeding, done heaving skimming, weekly water changes, and have a pack of purigen to drop my phosphates all my parameters are good so I have no idea what else to do. I bought a pack of chemiclean but really don't want to resort to any chemicals for this issue but my patience is running thin. Any help and advice is much appreciated!!
