Ok, it says the active ingredients are sulfamethazine and trimethoprim. Says you can use it to treat dropsy, etc. I also bought some anti-parasitic food and he ate a little bit, but I am going to try soaking it in garlic. The other fish love it though LOL.
So you mean do a dose, do a partial water change of 50% (normal pwc) and then dose again? Or just dose what I took out? I use 4 capfuls for the 20 gallons, so I would redose 2 capfuls after correct?
Thanks for your help.
