Hypo at a level (1.008/9) to kill the infective stage of ich can be hard on the kidneys because you are approaching a level that can negtaively affect the osmoregulation of the fish itself. Hypo is also a misnomer: 1.017 is also "hyposalinity" (lower than natural sea water) while it would have no affect on ich it does make it easier for the fish itself to osmoregulate.
Could an even lower salinity have potentially fatal effects? (Again with a faulty reading perhaps).
