Pond Boss Forums POND CONSTRUCTION Soil questions Alum on new pond floor

That is the way you are supposed to do it. Take a soil test and tell the lab it is a new pond bottom.

That is what we do. Run the spreader truck across the bottom in a large pond or spread all around the perimeter if the banks are too steep. Back up to edge and let r rip.

In my non-professional opinion based on nothing other than opinion unless you apply the lime measured in inches deep, adding too much will only make it last longer. If you have acidic clay it is probably about a 5 Ph with a buffer solution requirement out of this world. Get it tested though and they will give you a recomendation. Good luck getting a representative sample.
