In collaboration with Hopkins Marine Station and the Center for Ocean Solutions, Monterey Bay Aquarium Research Institute is developing a swFOCE system to examine the effects of ocean acidification on shallow subtidal communities in central California. swFOCE will use a shore side station for the control system and production of CO 2 enriched ...
A tubular reactor consists of vertically or horizontally arranged tubes, connected together, in which the algae-suspended fluid circulates. The tubes are generally made out of transparent plastics or borosilicate glass, and the constant circulation is kept up by a pump at the end of the system. The introduction of gas takes place at the end ...
Recirculating aquaculture systems at the Virginia Tech Department of Food Science and Technology. Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1]
The balance of these carbonate species (which ultimately affects the solubility of carbon dioxide), is dependent on factors such as pH, as shown in a Bjerrum plot.In seawater this is regulated by the charge balance of a number of positive (e.g. Na +, K +, Mg 2+, Ca 2+) and negative (e.g. CO 3 2− itself, Cl −, SO 4 2−, Br −) ions.
The typical hobbyist aquarium includes a filtration system, an artificial lighting system, an air diffuser and pump, and a heater or chiller depending on the aquarium's inhabitants. Many aquaria incorporate a hood, containing the lights, to decrease evaporation and prevent fish from leaving the aquarium (and anything else from entering the ...
These three pumps are: (1) the solubility pump, (2) the carbonate pump, and (3) the biological pump. The total active pool of carbon at the Earth's surface for durations of less than 10,000 years is roughly 40,000 gigatons C (Gt C, a gigaton is one billion tons, or the weight of approximately 6 million blue whales ), and about 95% (~38,000 Gt C ...

A newly set up baffle filter, under a large volume cichlid aquarium. Baffle filters are similar to wet and dry, trickle filters in that they are generally situated below the aquarium. This type of filter consists of a series of baffles that the water must pass through in order to reach the pump which is returning water to the aquarium.
