ahhhhhhh, you have answered my question!!! Resuspension is not likely. That is the answer I was looking for. In other words, as King Bob says, "that's just a bandaid"!! We do not want to continue applying alum (expensive) to our lake every year. On top of that, there is the possibility of a fish kill if the PH drops to low. I understand alum, just don't understand it's results in certain conditions. Your fingerling quality may soon be lunker......keep it up. Thanks. ;\)
