## Description

API Pond Melafix, 16 OZ : desertcart.ae: Patio, Lawn & Garden

Review: 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.
Review: 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.

## Questions & Answers

**Q: Will this treat Ick/white spots**
A: This will not treat the freshwater Ich (Ichthyophthirius multifiliis) parasite. If you are looking at your fish and it is not the tell-tale pin-point ich spots, it may be a bacterial infection that the Melafix will be helpful with. It may be worth knowing that this will affect the marine form of ich (Cryptocaryon irritans). If you would like assistance with an appropriate medication to use on your fish or any other questions on our products, feel free to call us at 1-800-847-0659

**Q: Need to know how much to use for a large pond. How many oz per 100 gallons?**
A: Hi Kate, The label says to add 5ml/50 (10ml/100) gallons daily for three days when adding new fish. Use the same dose for 7 days when treating infections unless it's chronic infections, then you double the dose. It also says 1/4 cup for 600 gallons. Our pond is about 400 gallons and I used just under a quarter cup. Be prepared for the foaming but it does go away. We dosed in the evening and most of the bubbles were gone by morning each day. We have two streams with short falls running 24x7.  Hope this helps.

**Q: Can I use it on saltwater fish**
A: YES! I have used this product for years with saltwater tanks, even at double dosage rate. That includes reef tanks, and the most severe reaction the corals have ever had was to close their polyps for an hour or two. Be warned, this medication will cause bubbles in the water temporarily, but they go away after a little while. Make sure you adjust the dosage for your tank, as pond melafix is a more concentrated form of melafix than regular or marine. If you have a small tank, I would just use either regular or marine strength.

**Q: How many years do these last? I am trying to get the bigger bottle**
A: WELL THIS Bottle only treats up to 4800 gal.  So it depends on pond size. and how many fish are in it.  Follow directions on the bottle...

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.
