Haha! None taken. I'm really pretty diligent with my aquarium maintenance. I do a 50 percent water change every week, dose everyday...I get my arm wet pretty much on a daily basis.
Believe it or not, it all started with one tiny piece of duckweed. There's barely any on the surface, and because I don't change my DC indicator fluid but once every 6 weeks or so, I just never noticed that some duckweed had made it down there. I just thought it was funny, as it seems that stuff will make its way into every nook and cranny available!
