I plan on making a 4'x4'x2' tank and am fortunate enough to not have too much of a budget. I just need some advice on where to start. Maybe some neat ideas for aquascaping (I think its called?). I'm not worried about particular inverts or fish at this point just the lay out of the tank in particular. I was thinking a center overflow as this would allow for a 360 degree viewing area. I am building a house and need to know some specifics about the location of it also. I was thinking about making the entry large enough for it so all could see it upon arrival. Let me know whether or not the center overflow is a good idea, or if it's possible at all. Also, is the entry an ok place for it to be located?
