We have a water well and Allen plans to run a water hose to a tub where we will make the alum slurry to broadcast on the pond. It doesn't make any difference if it's a slurry made with well water versus slurry made of pond water does it?
Also, we have a make-up pipe run to our pond. In the summer, have a timer set to run well water into the pond weekly to keep the water level up. Will that have a negative effect on our clarity once the water is clear?
