Not sure if this is the right area but here goes. I still have some leakage in my larger pond and I have a few springs around my property. What I would like to do is pour a dye or chemical in the pond and test to see if any traces are present in any of the springs. This might help in determining which way my water is going. I don't think it will be enough to just go by sight. That is why I want to be able to trace down to the smallest levels. Does anyone know of anything that would work? I tested with a pool tester for ph levels and they aren't even close but if only a little pond water is making it to the spring it might not raise it much. Appreciate any advice.
