Good when combined with melafix
Combined with nelafox this does wonders for hospital tanks and sick fish. Doesn't effect plants and you still need to do a partial change of water after a week. Good quality medicine

Natural solution for fish fungus
API Pimafix works great for treating fungal infections in freshwater or saltwater fish. The liquid formula is easy to use and doesn’t cloud the water. The scent is a bit strong at first but fades quickly. Best of all, it’s made with natural extracts, perfect for those who want to avoid harsh chemicals. Follow the manufacturer’s directions to avoid overdosing and keep your fish healthy.

I think it works
Some people say that this stuff is snake oil. But I've had good luck with it. I think it actually does work, regardless of what you read on the internet. As does the sister product Melafix.

Pimafix + Melafix for new fish - a MUST HAVE
I recently bought five fairly large fancy goldfish (3 Yuan Bao Orandas-females, 2 Lionchus-males) that were quite expensive. The breeder quarantined them for 14 days before they were shipped but I guess the shipping stressed them out because there was some cotton growth, tiny white ones, on their tail-fins and base of their tails, and one had it on her body. They got fungal and bacterial infections although their tank in my home is clean, salted (1 tbsp per 5 gallons) and disease free. I quickly ordered Pimafix and Melafix although I still had some for 'just in case' so I wasn't surprised by the pepperminty scent. Also, I didn't want the newly established bacteria culture harmed by harsher medicine. I didn't need to remove any active carbon since I didn't put any in the canister filter or HOB but if you do, remove these first! I just have Algone packets in there to keep water parameters stable and water clear. Algone doesn't remove medicine! Already within two days, the two wen-rich Ranchus were swimming happily sans cotton growth, but I kept them in the tank for a week to be sure before putting them into the healthy 'male' tank. Two Yuan-Bao Orandas had it really bad, though. They were floating nose-down. After three days, the red one is healthy and fine. Mousse, the chocolate one, is still struggling with an internal bacterial infection but NO MORE COTTON GROWTHS! I have four more days to go before finishing this treatment after which I'll put in active carbon into the canister filter and do a 30% water change. Pimafix and Melafix really are must-haves for fancy goldfish keepers and serious aquarists! Always have these on hand and use these first before deciding to go for the more harsher medicine like Jungle (now Tetra) Fungus Clear (although this works wonders for more progressed diseases).

Worked for me.
I used this with Melafix. They worked great together. Cleared up open wounds, cottony fungus, eye problems. I woul recommend

Not impressed!!
These products seem great in theory.. Huge name! But after a year of occasionally treatment we've seen no real evidence of this helping our pond/aquarium. Without confidence, we won't be using these products again.
