I will follow this. Etunes, can you send me a link to a tank size calculator. I forget what topic it was posted on that I made. Last time I calculated my tank, it read 55 gallons but from the picture on your first post, my tank looks the same size empty as yours. I am kind of convinced that it might be the same type too. I'm not sure what my tank's brand is though since I got it used and it doesn't have any tags other than saying it is tampered glass.
