Institution: University of New-Brunswick in Saint-John Location: Saint-John, New-Brunswick, CANADA Contact: Dr. Rémy Rochette Habitat: Saltwater Type of rearing unit: TWO TIDE SYSTEM RECIRCULATING UP TO 99,9% OF THE WATER              Unit description: Four aquariums filtered, cooled and heated independently. Each aquarium have a tide simulation system; At maximum flow rate (2 lpm), the 99.9% recirculation system requires no more than 0.12 litres of make-up water per hour. Recycled effluent passes through a rapid action cartridge filter (16 microns) to remove fine solids and dissolved organics. Degassing column (air intake included) for CO2 removing; A thermoelectric module maintains a temperature range of 5-25ºC, provided that air temperature is at 15ºC; The electronic digital temperature controller (Enviro-monitron) adjusts precisely (+0.1ºC) the water temperature. One electronic controllers Enviro-monitron (Tide version) control the Tide and the Temperature for two aquariums; The Tide simulation system consist: 1 water level sensor; 1 peristaltic pump (24VDC); Each aquarium is divided in two tanks: one experimental tank (front tank) and one tank to accumulate the water (rear tank); Capacity to regulate the water level from 3 to 56 cm; Capacity to choose if the tide begin at low water or high water: Capacity to choose duration between low and high water (300 to 420 min) and the number of consecutive flow.
