Years ago, maybe in 1996, I asked here about how to keep a small pond clear. Great Dis'ers helped me out, we got an ultraviolet filter which does the trick. Now, there must be others with a pond. How about posting about your pond, pictures. I will post a picture of my pond after we were gone 3 1/2 weeks. There was rain, and I think my house watcher did put water in it. I am thrilled. My small pond gives me lots of pleasure. There are 4-6 regular gold fish in it, have not bought any since 1996, they have lived a long time, get a few babies ever few years. Frogs come to stay awhile every so often. We live in the suburbs, but there's a creek about 1/4 mile away, I suppose that's where the frogs come from.
