I do not have a quarantine tank in my apartment... so i have been using 5 gal buckets with an air stone in each one. I change the water out every other day and so far i have not seen any problems with the fish i have in them. I medicate the water every other day with quick cure and I am about to start an antibiotic treatment for the last week of qt. Is this even an affective way to quarantine? Am I doing any good at all?
