Last winter my pond was losing between a quarter and a half inch per day. This winter my water actually came up a bit (I have had geothermal running in both winters). The only treatment I used was one unit of SoilFloc along my dam. Prior to treatment I had constantly ran 5-10 gpm into my pond PLUS the geothermal water. Now I haven't added any water other than the geothermal since treating the pond in August. Seems to have worked a miracle for me.
This spring a hope to add a bit more SoilFloc in a few other areas I think I may be losing water so that my geothermal actually causes more overflow.
