I just had a 3/4 acre pond dug in september or 2011. its almost full thanks to the lovely ohio weather!!!! Any way I had all my downspot and foundation drains ran into the pond to help keep it full and my water softner discharge line (for the regen cycle) is tied in to the down spots. I have not ran any water test yet but am curious to know if this will casue a potentional problem. thanks for the help in advance. Chris
