CO2... and a weird slime...
About a week ago I set up a "Hagen CO2 Natural Plant System" on my 29 gallon planted tank. It's been working great! Bubbling it's little head off, traveling up the cool ladder gizmo like there's no tomorrow. Everything going swimmingly until I turned on the aquariums lights this morning...
From out of nowhere an odd cloudy/white "scum" showed up on the bottom "rung" of the ladder, blocking the bubbles there until they get large enough to force their way through. The substance looks a bit like slug slime.
I'm wondering if anyone else has experienced this odd situation with their co2 diffusers or "ladders". Anyone here have any idea what this might be? Could it be a colony of anaerobic bacteria setting up house?
It's all a bit alarming, and very intriguing! Guess I'll try to siphon it off when I get the chance this afternoon.
Thanks for any information!
