I put in Bentonite in combination with Soilfloc in 2016, and it all sank to the bottom fairly quickly, wasn't muddy for more than a few minutes. Last winter my pond had 10 foot visibility for a few days. The Soilfloc/Bentonite combo did not help with the leak long term. In fact, it seems slightly worse than it was in 2016.
