Take the following as truth: Hypersaline brine and artificial seawater can be used with Champia parvula only if they are accompanied by at least 50% natural seawater.
Then the following statement: "Champia parvula can not be used with hypersaline brine or artifical seawater, even if they are accompanied by 50% natural seawater." is true, false, or inconclusive?
