## Description

API MELAFIX Freshwater Fish Bacterial Infection Remedy 1.87-Liter Bottle : desertcart.co.uk: Pet Supplies

Review: Gentle, effective, and easy-dose—solid remedy for fin rot, wounds, and tank recovery. - This bottle’s made to handle mild bacterial issues—natural tea tree extract that treats fin rot, ulcers, and open wounds without hammering your biofilter. Geared toward freshwater setups with sensitive fish or planted tanks. Doses clean, smells herbal, and doesn’t cloud the water. Works well in recovery setups—post-transport stress, minor injuries, or when fish start showing signs of wear. Ideal for van stash, pet kits, or home aquariums where you want low-impact treatment. Bottle’s easy to measure, and the 473ml size lasts through multiple rounds. Best used with good aeration—MELAFIX can reduce oxygen slightly, so keep your pump or air stone running. 👍 Pros ✅ Natural formula—tea tree based, gentle on fish ✅ Treats fin rot, wounds, ulcers, and abrasions ✅ Safe for plants and filters—no harsh chemicals ✅ Easy dosing—clear instructions on label ✅ Large bottle—covers multiple treatments 👎 Cons ❌ Mild strength—won’t fix severe infections ❌ Herbal scent—noticeable during dosing ❌ Needs aeration—can lower oxygen levels
Review: Definitely helped my poorly fish . - Bought this in hopes it would help my young Koi that just hasn’t been well since it was gifted to me 3 months ago . I had no idea what was wrong & we have no aquatic vet close by so after googling symptoms in great detail & doing some research it kept coming back as bacterial infection. I’ve had my other fish 20+ years & never had to use any chemicals in my pond or treat any of my fish .. Decided to give melafix a go & im really glad I did . I isolated him in a tank & im currently on day 6 of the treatment . He’d been bottom sitting in my pond for weeks , he’d never come up for food at feeding time & he spent 24 hours a day hiding behind my pond plants . As you can see in the video I took yesterday he’s now swimming around perfectly normal & happy , Ive been using koi flakes to feed him whilst he’s in the tank (usually use MediKoi) & it’s the first time I’ve seen him eat since he fell ill . The melafix also cleared up a red bloodshot patch he’d got underneath his body within the first dose of treatment . He’s not stopped swimming around & playing with the bubbles from the air stones 😂 I’ll be gutted when I have to put him back in the pond . I’d definitely recommend this stuff . I thought I was gonna lose my fish he was so lethargic & unwell but it took just 3 days of this stuff & I saw positive signs . Just to add , it did make the water go incredibly cloudy and my koi did start rubbing a bit against the airstones which can be a side effect to using melafix . I did a 25% water change and added 2 tablespoons spoons of pond salt , this helped with any irritation / stress .

## Questions & Answers

**Q: This site list melafix from two different venders, mars and pond care. big difference in priceing. are they the same?**
A: I've used several different brand types of melafix and found that they work just the same.

**Q: Is it safe to use post-expiration? In other words does it turn toxic to fish or simply starts to lose the effectiveness?**
A: I would think if this is not very much over date, like 6months or so, it would be fine. If it is still sealed, it will be like new or almost. If it is older, it probably, hate to say as this, but I would think it will be okay to use, and just be weaker or maybe not. If you are in doubt, I would buy a new one to be certain. In the past, they never put dates on anything, and now a days they do and the things were used and were okay. Best answers I can give you. Good luck with your issues.

**Q: I guess my butterfly goldfish has fin rot. How should I treat it? It is in a pond with other healthy fish.**
A: If the other fish are healthy. Then you should remove it in to a isolation tank. Be sure to use the pond water when you fill it. There are instructional videos on YouTube that will show you how.

**Q: How is this different from regular strength? They both have 5% concentration in a 64 oz bottle.**
A: My advice is to please ask a professional breeder for direction. Off the self purchases is "gambling" to me!
Best wishes to you and the Fish :)
