How many watts are your lights?
Good thing you put your assistant for a size comparison & same with the soda bottle.
I left my lights on for at least 60 hours but I didn't have any growth like that.
Other than the 100 plant stems in my tank, there's no other inhabitants.
I'll fill it with my bettas after I'm done partying this weekend.
Anyway, do you have any current photos of your entire tank? The two photos make me curious to see what your setup looks like now.
The pictures I've seen in your gallery of the 60+ tank are from 2009.
