I've got red slime in my tank and it doesn't seem to be going away. I did a search and have been doing the water changes, reduced my light cycle by an hour (9AM-3PM) and reduced my feeding. I checked my water at the LFS to make sure my readings were the same. Any Suggestions? What causes this? I've tried scraping it off the glass and sucking it out but it keeps coming back. Please help.
