There's nothing harder to arrange than "random".
The ring likely isnt Co2 resistant? The level of Co2 in the water column is causing the tubing to react. Use Co2 safe tube and it will go away. This is common with non polyethelene (Co2 safe) tubing.Yeah, it's just to stop my floating plants from swirling about, they don't like it. The problem is the tube somehow reacts with my water and gives off a white slime!
