I use window screen on the pond water suction strainer and on the slurry pick-up....if the Alum is not completely dissolved, it falls straight to the bottom like a rock and does not flocculate.
Hydrated lime dissolves and disperses throughout the water column.....alum does not. Alum goes into a slurry when heavily agitated in water, and then falls to the bottom after being sprayed onto the pond
