[attachment=599:name]Here is an older pic of my 92 G corner bow, open the one on the next post it's much easier to see. It has filled in alot up front since this. No grades or hills or anything, but the most important theing to keep in mind is having tall, hardy stuff in the back to hide the mechanicals as that is the only place for it to come in and out. Corner tanks are great, smaller footprint, better viewability (if that's a word, I guess it is now.....) Lighting is difficult to spread evenly, but it can be done. Flow and distribution can also be a challenge, play around with it, you'll probably want a powerhead in addition to the filter outflow. I point my outflow down and at the BACK of the tank to get to the back plants, the powerhead point straight forward and centered for the front stuff. Seems to work fairly well. Good luck and enjoy, corner tanks are very cool!!
