Im not quite sure as to how this falls on a scale of low - high light rating, but id say its probably medium where its at right now. If you follow the watt per gallon rule on this tank its extremely high light, but I think that rule goes out the window on tanks of this aspect ratio. The lights are reasonably bright, but ive got them up high enough that it doesnt cause too many algae problems.
As for the window, i doubt it provides any amount of light that anything can grow from...its an eastern facing window so I like the fact that it gives the fish a gradual light increase in the morning until the lights turn on. By the time its 12ish or so, theres not too much light coming in. If it were a southern facing window with not as many trees outside of it...that may be a different story.
The co2 system cost me about 40 dollars. Somewhere around there. Probably the best 40 dollars Ive spent on this hobby so far. Props to Jaggedfury and his thread explaining how to set it up. Will forever be in debt to him. Ive had it up and running probably over a month now and the pressure hasn't dipped yet.
