Gentle, effective, and low-fuss—solid treatment for minor fish injuries and tank recovery.
This bottle’s geared for freshwater setups—uses natural tea tree extract to treat fin rot, open wounds, ulcers, and mild bacterial infections. Ideal for tanks with sensitive fish, planted setups, or when you want to avoid harsh chemicals. Doses clean, smells herbal, and doesn’t cloud the water.Works well in recovery tanks, post-transport stress, or when fish show signs of wear. Safe for filters and plants, and won’t knock your biofilter. The 240ml size is spot-on for small to mid-sized tanks—easy to store in van stash or pet kits. Best used with good aeration, as MELAFIX can reduce oxygen slightly during treatment.👍 Pros✅ Natural formula—tea tree based, gentle on fish✅ Treats fin rot, ulcers, and abrasions✅ Safe for plants and biofilters✅ No clouding or residue✅ Compact bottle—easy to store and dose👎 Cons❌ Mild strength—won’t fix severe infections❌ Needs aeration—can lower oxygen levels❌ Herbal scent—noticeable during dosing

Love it. Does the job.
Great product. Got this too be prepared for any open wounds and such, and a couple of days after I got it one of my goldfish got a small wound on the belly from derping around I think.Used this and after 12 hours I could already see a difference and it worked great.The smell when you open it is very extreme when you open it. Very mint or something along those lines. But ones in the water you won't notice it.I took of a star becauce it came and had leaked in the package. The lid was not secured properly and the plastic seel was also loose. Yet only a tiny amount of product had come out so wasn't too displeased (see picture).All in all, great product would buy again if it ever were to be necessary.

All good
I bought this because one of my fish had minor cuts on his side, presumably from swimming too close to rocks and caves. This definitely seemed to help and the cuts seemed to have cleared up after a few days.

Great stuff.
Great stuff helped heal my fishes pop eye after antibiotics. Great for fin problems. Easy to use and dose once you figure out how much water you have in your tank. Smells great too.

Helps sick fish
I had a bit of a problem with my golden rams getting dropsy, I used this for 7 days and did a water change and it's made the tank better again, it even smells nice for the tank.

Good for the med kit
It really helps my fish after breeding when one or two have fin damage so treat for a week before big water change

Great size
Exactly what I was looking for my freshwater aquarium to treat my fish.The bottle was bigger than I expected - the amount of liquid as advertised.
