While duration of treatment depends on type and severity of infection, it is recommended that extended medication baths continue for a minimum of 5 days but not more than 10 days. Discontinue treatment if no improvement is noted within 5 days. To remove harmless yellow color, change 20% of water and use charcoal filter until clear.

My dog was ill and I really didn't want to have to spend time and money to take him to the vet. Luckily, a friend told me about this website, where I can order antibiotics online. It may say it is for fish, but it worked well on my dog and he seems much better, not lounging around, but full of energy once again! Thanks!

Thank you...and my fish thank you. I have several aquariums in the basement now, and every one of those fish had something, when I got them. Instead of returning them to the store, I did something that helped them.

I have had bacterial problems with most of my fish and this is by far the best anti-bacterial product I have used. And its pharmaceutical grade.
Lightning fast shipping. I got it the day after I ordered it and I live in Michigan!
