It is easily soluble in water (both fresh and salt) but it drastically decreases the pH of water, increasing the acidity, which may be toxic for fish. Sodium bicarbonate can be used to buffer the solution to a pH range of 6.5-7.5. Usually an equal amount of buffer is added to attain a neutral pH. [5]
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.
Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protection Agency (EPA) for use as a pesticide and its effectiveness as an algaecide in ponds has produced mixed results during university testing in the United ...
Saltwater may have a pH of 7.8 or higher, so to reduce the pH carbon dioxide (CO 2) is used. The reaction formula is: CaCO 3 + H 2 O + CO 2 Ca 2+ + 2 HCO 3 −. Inside the reaction chamber, a calcium rich media , mainly CaCO 3, is forced into contact with water injected with carbon dioxide (CO 2) in order to create carbonic acid (H 2 CO 3).
Aquarium filters are critical components of both freshwater and marine aquaria. [1] [2] [3] Aquarium filters remove physical and soluble chemical waste products from aquaria, simplifying maintenance. Furthermore, aquarium filters are necessary to support life as aquaria are relatively small, closed volumes of water compared to the natural ...
The liquid fish hydrolysate process minces the whole fish, then enzymatically digests, then grinds and liquifies the resulting product, known as gurry. Because it is a cold process, gurry putrefies more rapidly than fish emulsion and needs to be stabilized at a lower pH, requiring more acid.
