Hi..the instructions on bottle says half dose for freshwater. What if im running hyposalinity during treatment? Do i mantain the dosage for usual saltwater?You redose once after 48 hrs and then copper should be at therapeutic. Measure with a Seachem or Salifert copper test kit to confirm that. However, once a therapeutic level has been achieved (0.5 mg/L for Cupramine) then you shouldn't need to add more unless doing a WC. Also, note that any rock/sand in the QT will make it difficult to achieve (and maintain) a stable Cu level due to absorption.
