Hello again! i just went to a local ace hardware and suprisingly enough to me they actually had silica sand! it was 30 mesh thoughMy main question since i couldnt find anything about the actual grain size or anything does anyone know if 30 mesh is too fine? id imagine it wouldnt matter much the size if the grains but i figured if it was too fine it coule just wash through the peat while.
