## Description

Treat bacterial infections and promote healing in pond fish with this natural, botanical-based remedy. Helps repair damaged fins, ulcers, and open wounds quickly.

Review: From lifeless to spring chicken - read my review and view images - Our fish was showing signs of septicaemia with blood spots, scales peeling away, very lethargic, not eating and fins that looked damaged beyond repair, so after a full tank change with 24 hour settled water, all plants removed to prevent further damage from brushing past, I followed a set routine of daily treatment using this treatment, within 2 days she became more active, and obvious signs of repair were visible, blood spots were disappearing and her fins were slowly starting to move more freely. It’s been 10 days and apart from the damaged scales on her side that are still healing, she’s back to herself, swimming, begging for food every time she sees anyone, safe to say my son is super happy that he’s not got to say goodbye to pepper just yet. Can’t recommend this product enough, well worth the money, the size was plenty for what I needed, but I’ll just continue to use it bi daily for the next few weeks to ensure that it is fully treated and doesn’t come back. And because she’s eating again equivalent to a St Bernard ( if we let her ) there’s less debris in the tank so the tank has stayed clearer. Also I’ve just noted that pre treatment her back was arched and looked so poorly, today she’s back straight, able to buoyant herself easily. I have attached pictures from day 1 to day 10 to show the difference. Absolutely superb result.
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: hi will this help whit spot for koi? also will this knock back the good bacteria in pond?**
A: No it won’t help white spot, I use WS3, melafix is a natural treatment, tea tree oil & doesn’t affect anything, good luck

**Q: Will this treat flukes and fungus at the same time in a koi pond.**
A: I don,t know about flukes, it,s meant for bacterial infections. Hope that helps.

**Q: How much should I put in my 3000 litre pond?**
A: Well I have a 180 litres tank and I put 25 in am not sure sorry

**Q: How does pond version differ from aquarium version please.. wanting to buy bigger bottle for regular use in my aquarium**
A: Not sure as I do not have an aquarium. The pond version suggests 15 ml per 567 litres to be given daily for 7 days when fighting infection. 15 ml is about 1 tablespoon.
