TerraPond ion charged minerals can be added to aquariums, ponds, and water ways to naturally clean water, nourish fish, improve fish color and vitality, and reduce disease risk. All fish and other animals such as birds, ducks, and turtles, along with aquatic plants thrive in pure, clean water. TerraPond ion charged minerals clean water without harmful chemicals. Instead TerraPond minerals use their negative charge to seek out and bond with positively charged impurities, toxins, bacteria, fungi, and parasites. Positively charged impurities are surrounded by mineral particles designed by nature to be one micron is size, considered impossible even by modern technological standards. Ion charged minerals cut off nutritional supply and force impurities to sink to the bottom of the tank or pond. Later impurities will turn into gas and/or basic elements that are no longer toxic to fish and animals. TerraPond minerals are so nourishing to fish like Koi, it will brighten fish color while increasing health and vitality. Adding minerals to aquariums and other water features will start working right away, but may take a day or two to finish cleaning water impurities. It will be worth the wait as water turns clear, remineralizes, and levels off to a healthy pH for fish helping to increase longevity.
