The tables below present an example of an artificial seawater (35.00‰ of salinity) preparation devised by Kester, Duedall, Connors and Pytkowicz (1967). [1] The recipe consists of two lists of mineral salts, the first of anhydrous salts that can be weighed out, the second of hydrous salts that should be added to the artificial seawater as a solution.
Water conditioners are formulations designed to be added to tap water before its use in an aquarium. [1] [2] If the tap water is chlorinated then a simple conditioner containing a dechlorinator may be used. These products contain sodium thiosulfate which reduces chlorine to chloride which is less harmful to fish.
The "dilution factor" is an expression which describes the ratio of the aliquot volume to the final volume. Dilution factor is a notation often used in commercial assays.
Stock tanks can be repurposed as backyard pools, or "stock tank pools," using chlorine tabs and a filter pump. Stock tanks are increasingly used as "rustic" backyard above-ground pools, or "stock tank pools" by retrofitting a filter pump [4] and adding chlorine or stabilized hydrogen peroxide [5] to keep the water clean throughout the summer.

[15] k 1 is the rate constant for chemical uptake from water at the respiratory surface (L*kg −1 *d −1). [15] C WD is the chemical concentration dissolved in water (g*L −1). [15] k 2,k E,k G,k B are rate constants that represent excretion from the organism from the respiratory surface, fecal excretion, metabolic transformation, and growth ...
By far the most frequently used products are formulations for mixing with water then applying as sprays. Water miscible, older formulations include: EC Emulsifiable concentrate; WP Wettable powder; SL Soluble (liquid) concentrate; SP Soluble powder; Newer, non-powdery formulations with reduced or no use of hazardous solvents and improved ...
Sour cream is another milk substitute similar to yogurt, and it even has the added benefit of tenderizing baked goods (like cake, muffins or quick breads). Keep in mind, though, that it will add a ...
Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions.
