We are going to install a small pond in our backyard.
It will be one of those bio-eco systems that do not require massive
filters and chemicals.
Town code states it can't be over (I think) 18 inches without a fence
around the properity or pond.
We don't want the fence so we want to keep it to a max depth of 18
inches.
These bio-eco systems require fish and I am not sure 18 inches is deep
enough to protect them in our cold winters here on Long Island.
Any ideas or thoughts?
