I had a large koi (2ft) that got out of the pond somehow and I went out into the backyard to find the dog chewing on him. We thought he was probably dead, but put him back in the pond and he slowly swam away. I bought this antibiotic to hopefully help heal the two injuries he had from the dog. The only downside is that you have to turn anything like UV lights off while you are using it, so you might get some green in your pond while those are off. However, this is about a month later, and my fish is doing great. The injuries are healed over. Note: the antibiotic does create a lot of "suds" on top of the water, just FYI. But since my fish didn't die, and the injuries healed over, I am assuming it was due to this product.

El producto es muy bueno, pero caro si piensas en que es muy poca cantidad y además le sumas que has de pagar aduanas, siendo un producto que llega de Europa, no entiendo el tema aduanas, la primera vez que lo compré no tuve que pagar ese suplemento, por eso lo devolví, me parece que el costo del producto ya es elevado como para pagar de más.

This is a very good concentrated product if you have many aquariums. It works to cure physical damage on fish and to treat bacterial infections. I recommend this product.

Great value for your money, cured a few wounds my cichlids obtained from battling each other. A staple that anyone must have if having fish really, but its essentially just some tea tree oil with other natural additives that help heal... like aloe. This is a much better value than regular melafix, since its very very concentrated, same thing as seachem prime vs seachem safe. I use 7 Milliliters in my 75 gallon tank, and have no problems whatsoever.... 1 ml per 10 gallons, it does have the usual measuring cup on the top of bottle too.

Update: my fish is still alive today. His growth was stunted but alive and well! This product along with pond salt and Pimafix antifungal saved my fish. My koi fish developed dropsy, had no clue what that was at first. I assumed he would likely die based on all that I read about it. Not sure what the cause was but I figured I would try to treat the fish. Isolated the fish, was sure to oxygenate the water/container he was in, gave him a salt bath according to the instructions on the pondsalt container, added ponsalt to the pond as well. Put my fish back in the pond and treated the pond along with the other healthy fish according to the instructions on the bottles. His swelling gradually got better and he's alive and well today. It's been about 2 months since I treated him. All 3 products did not affect the pond plants or the other fish. Great products!
