Thanks for the nice comments. I have a North facing window that never receives direct sunlight, so the tank is never too hot. The plants benefit from the reflected light from my neighbors house. I have had the tank running for over a year now, and the Crypts all seem to be thriving... The cord you see is for the submerged powerhead in the tank. The position on the blinds seen in the photo never changes either. I will try to snap a better photo when the sun is out, and I won't use the flash on my camera. If you have any other questions, shout them out!
(I should have cleaned the tank before the photo was taken...)
