Cecil,
We are about to finish our house and I am getting ready to set up my system in the basement so it is ready for the fall. I am looking a possibly a square 180 gallon tank because it will fit better in my space. Do you see any problems with a square tank vs. a round one?
It won't self clean very well and you'll have solids sitting on the bottom in what are known as "dead zones." You can do it but you will be limiting your carrying capacity by not removing waste efficiently.
