If you feel a repeat dose is necessary, check your diagnosis carefully using the Diagnosis Tool on our website; a different medication may be more suitable. Allow 7 days after medicating and perform a partial water change before re- treating or treating with another medication.
Always treat when you have time to observe fish and take appropriate action in the unlikely event of a bad reaction.
