So, I have another question. My ponds are right next to each other. Pond 1 currently has a siphon on it and it is working great! Thanks for the help. The only way to get a siphon going on pond 2 is to run it into pond 1. My original plan was to put another siphon on pond 2 and drain it into 1 and then out of pond 1. However, I had another thought and wanted to run it by the professionals. Could I drain pond 1 as low as possible then nuke with lime. Then set up a siphon with some type of fish Gaurd pond 2 and drain it into pond 1. Using the water to refill pond 1 but not getting the unwanted fish. Then nuke pond 2. Is this possible? If so, what could I put on the 2 inch pipe to insure no fish transfer.
