Yikes. That's some crazy bacteria you've got going on there. :/
It creates a lovely shimmer effect. It's quite nice to see the light dancing on the wall. I'm not sure how it causes in-tank objects to shimmer, but I'll definitely report back once I get it filled and planted. If it's anything like spotlighting my 20L at night with my iPhone's flash LED via app then it should shimmer nicely. Frank has his setup...maybe you could ask him?
