A term used to describe the many necessary elements found in water that are needed for proper plant and fish growth, although they are usually only needed in very small amounts. Among them are calcium, strontium, iodine and ozone. These are usually replenished with partial water changes and food or specific additives.
Chemical elements present in exceedingly small quantities. (PPM.
Minute substances found in water,that are needed for proper plant and fish growth. Usually replenished with partial water changes.

Those essential elements that are needed in only very small amounts.
Chemical elements which are required, usually in tiny quantities, for healthy growth of fish, plants, and invertebrates. These elements are normally supplied by regular water changes or in salt mixes for marine aquariums, but in certain cases it may be necessary to supplement this.
Nutrients required by a plant to maintain steady and healthy growth (boron,copper, magnesium and zinc).
This term refers to five elements necessary for plant nutrition which are present in the soil in minute concentrations—boron, copper, manganese, molybdenum and zinc. To Top
Plants need the addition of small amounts of the elements zinc, boron, manganese, molybdenum, and copper. Lack of these is sometimes a problem and difficult to analyse.
Minerals of which we need only a small amount in our diet to remain healthy, for example chromium and selenium.
A group of chemical elements that are needed in minute quantities for the proper growth, development, and physiology of an organism.
Members of the set of ninety-two naturally occurring elements (such as selenium and silver) found in low concentrations, usually less than one part per million. Trace elements can be found in rocks, soil, and water.
Elements that occur or are found in low concentrations typically at the parts per million level. See micronutrients.
"Mineral elements that vital to the metabolism, particularly to the functioning of enzymes, including anti-free radical enzymes. They are present in the organism in very small quantities. Examples: Manganese: anti-oxidant. Zinc: in the event of deficiencies, skin is dry Silicon: bridging collagen and elastin fibres Selenium: an anti-oxidant."
A term used to describe the many necessary elements in a marine aquarium, although usually in very small amounts. Among them are calcium, strontium, iodine and ozone. (for purification).
Elements that occur naturally in small quantities in seawater. These are required for survival by many reef organisms, and include calcium, iodine, strontium, molybdenum, lithium, and barium.
