FritzZyme® Trace contains essential trace elements and electrolytes necessary for nitrifying bacteria. It fortifies RO/DI and tap water lacking crucial elements, providing the critical components needed for healthy biological activity. Developed after years of biological research, FritzZyme® Trace has been designed to supplement all commercial biological products. Trace elements in small amounts are vital to the development and health of living things, and without them nitrification can be hindered, leading to increased ammonia and nitrite levels. Reverse osmosis and deionization can strip away these elements, making some city water sources deficient.
