I put 50 of them in but yeah, it's very difficult for me alone to assess. This fall, I'll probably bring Mr. Banks out with his electro-boat and see what's going on. I'd be very interested to know but my "test pond" attitude relieves my stress and the stress was very high the first year I had this place. The pond, as a whole, is extremely difficult to manage considering all of the runoff from developments in the watershed.
