Based on what I am reading, I guess I am worse than most. I don’t like to leave finger prints on my skimmer cup after cleaning. That’s just 1 example. But there are certain things that don’t bother me as much like coralline algae on the glass as I view that as a sign of a healthy aquarium and quite frankly, my algae magnet doesn’t get it off the acrylic and I can’t use a razor blade as that will certainly scratch the acrylic. In addition, I was hoping this thread would have some tips on how to further feed my OCD. For example, what is the best way to remove manufacturer labels and the associated glue from plastic bottles so that I can apply my own standard labels? Soak in warm water?
