I'm going to use some cutrine plus to try and kill FA. Does anyone know what kind of impact it will have on the snail population? I have RES in my pond and I wouln't want to kill all of my snails. I seem to have a fair number of snails, my kids are always playing with them around the dock. I havn't caught any RES since I stocked the pond but I haven't really fished for them and I'm reasonably sure that some probably survived the initial stocking and I'm concerned about starving them if I kill all of the snails. I did a search for cutrine and read the threads but I haven't found anything that address this issue. Any help will be appreciated. Thanks, Joe Street.
