Test parameters. Environmental parameters during the test shall be maintained as specified below: (i) Water temperature of 18 ±1 °C. (ii) Dissolved oxygen concentration between 60 and 105 percent saturation. (iii) The number of gammarids placed in a test chamber shall not be so great as to affect the results of the test. Ten gammarids per liter is the rec- ommended level of loading for the stat- ic test. Loading requirements for the flow-through test will vary depending on the flow rate of dilution water. The loading should not cause the dissolved oxygen concentration to fall below the recommended levels. (iv) Photoperiod of 16 hours light and 8 hours darkness.
