If you have a pond as a water feature you know that perfectly murky pond water doesn’t come by just letting it sit there. You have to care for your pond especially if you intend it to include fish. Just like when you have them in a tank at home, the water has to be aerated. You might do this with a fountain or you could get your hands on a couple pond aerators specifically designed for the job. These things don’t have to be unsightly – some even just float on the water.
