FritzZyme Trace 8 fl oz
Trace elements are not required in large quantities but are vital to the development and health of all living things. Specific trace elements including calcium, iron, magnesium, sodium, manganese and others are part of the fundamental process of nitrification in freshwater aquariums. The lack of these critical elements can slow down or prevent nitrification resulting in elevated ammonia and nitrite levels that are harmful to fish and invertebrates. The use of reverse osmosis and/or deionization strip these elements away, and certain city water sources are lacking certain elements as well.
