Reliability: (2)published article, reliable with restrictions
Remark:
Potassium was added in a geometric series of
concentrations, from 5 to 12 concentration levels were used.
Test medium was natural Lake Superior water. The test was run
with and without food addition. Two parallel beakers were used
at each concentration. There was 10 daphnids less than 24h old
in each beaker at the start of the test. Test temperature was
18 ± 1 o C. A 16 h photoperiod was used during testing. Only
the result of test without food is referred.
