Well, today I had my first, and hopefully last, empty pond experience! It's been VERY windy. The wind was enough to disconnect the tubing that goes into my filter. I happened to look outside and saw water gushing. I have the pump elevated a couple of feet from the bottom of the pond, so there was still some water, but the pump was just beginning to suck air. Anyway, got it taken care of, and don't think I've lost any fish. But sure glad for having that pump where it was. For now, just going to by-pass the SKIPPY until I can come up with a more secure fitting. Whew!!
