The effluent, which is now rich in elements from the dissolved media, is returned to the reef aquarium where the elements are consumed by organisms, primarily corals when building skeletons. The reactor dissolves the calcium-laden media to provide bicarbonates HCO 3 − (alkalinity) and calcium (Ca ++ ) ions at the same rate as consumed during ...
A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine ...
[7] After other researchers added calcium and/or connected their tanks to the ocean (which also supplies calcium and alkalinity), corals began growing again. Nevertheless, "problem" nutrients (ammonia, ammonium, nitrate, nitrite, phosphate, CO 2 , metals) were always kept at very low numbers.
The Berlin Method of biological filtration is a method for maintaining a clean and stable environment within a saltwater aquarium, typically a coral reef system. This method relies on the use of ample live rock (rock with live marine organisms and bacteria on or in it).
[1] [2] This process can increase sea surface temperature, decrease aragonite, and lower the pH of the ocean. The more humanity consumes fossil fuels, the more the ocean absorbs released CO₂, furthering ocean acidification. This decreased health of coral reefs, particularly the Great Barrier Reef, can result in reduced biodiversity.
Reverse osmosis is a more economical way to concentrate liquids (such as fruit juices) than conventional heat-treatment. Concentration of orange and tomato juice has advantages including a lower operating cost and the ability to avoid heat-treatment, which makes it suitable for heat-sensitive substances such as protein and enzymes.
Some of the best auto loans right now are offering 6% APR (or lower) for qualified borrowers. Anyone who wants to reduce their car ownership costs might want to start by improving their credit score.
A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration.
