Understanding TDS, Koi Ponds and Water Gardens

TDS or Total Dissolved Solids is the sum of all the chemical ions dissolved in the water. These substances are not necessarily "bad" chemicals. They're mostly minerals and salts in your pond. The TDS level is influenced primarily by the water source used to fill the pond. Some backyard ponds will have naturally high TDS levels while others will be low, depending on the water source.
