Pond Boss Forums GENERAL QUESTIONS Help geese

12 Geese in 2 1/2 acres will produce what most of us would consider an overabundance of natural lubricant, with associated possible water quality problems. I personally try to discourage permanant geese residents (there's no easy way for me to keep visiting geese out unless I patrolled 24/7). You might be more apt to be concerned if you 1) swim a lot, 2) eat fish a lot, or 3) have very fertile water that you don't want too much bloom in. If you have very clear (low fertility) water, maybe you want the geese.
