Gosh -- those are good ideas....wish I'd know you all when I had a Koi pond! This has brought back a funny with ours. DH went out that morning to break the ice. Do you know what ice sounds like when it's being broke up at 6:00 in the morning??????? Our neighbor told us later that he called the police because he heard glass breaking and thought somebody was breaking into houses or cars!!!! whoops!!!! LOL
