Thanks NNAFISH! I never thought of using a camera to help look for leaks. While I don't lose near as much water per day as you were when you started, and probably don't have a hole that big to spot, I wonder if a camera could help me find where my water is going. It would be nice to know what area to treat.
Can you tell me what dye you're using?
Is your pond very clear? It looks like it is. I would hate to spend that kind of money on a camera, and my pond not be clear enough to see anything.
