Questions about Kanaplex dosing
I'm using Kanaplex to help a friend treat her betta fish who we suspect is suffering from a severe case of fin rot (blackened, quickly disintegrating fin edges, with the infection now getting dangerously close to his caudal peduncle) The fin disintegration seems to have been checked by the medication and the little guy seems much more active, so we're hopeful that we've made progress! So here are my questions:
(1) The Kanaplex instructions say to dose once every 2 days, up to 3 doses. Does this mean that after 2 days, the dose is no longer active in the water column (and thus the next dose needs to be added then?)
(2) If the infection being treated doesn't seem to have subsided fully or satisfactorily by the end of the 3 recommended treatments on the package, can a 4th dose be given relatively safely?
(3) How long after a course of treatment (3 doses over 6 days) should you wait before giving another course of treatment, assuming the fish shows signs of deterioration after the Kanaplex is discontinued?
Thanks so much! Any information is really appreciated.
