The flow-through experimental system consisted of 15×8.5-L
polyethylene tanks situated in a 220-L water bath, arranged in 5 rows
of three tankswith treatments dispersed randomly. Thewater bathwas
maintained at approximately 18 °Cwith a 1-hp chiller and recirculation
pump. Three 60-L header tanks were used to precondition sea water
closer to the desired temperature and each supplied five tanks.Multiple
100 to 300-Watt heaters were used to thermostatically maintain the
desired temperature within each header tank, and float-valves were
used to regulate the supply of fresh seawater
