Why couldn't you set up a trash pump with the inlet in the pond just below the surface and the outlet where the problem spot is. Then while the pump is running pour small amounts of part a and b together. The pump will mix them up and spit out a cloudy whitish water out of the outlet. I did this with plain polyacrylamide (PAM) before and it mixed it up just fine but did nothing for the leak. I only used very little though no where near the 100 pounds one unit would be. I believe soilfloc has some sort of polyacrylamide (PAM) in it. It is used for all sorts of things and there are many different types. It is used in trench irrigation to stop erosion, it is used in diapers because it absorbs a lot more water than the weight of itself. Once it touches water it is a slimy mess. Just a thought.
