Is this safe around dogs if they accidentally drink water from
Answer by ChewyFeb 22, 2019
At this time, this remedy is not intended for the consumption of humans or pets.

Since Pimafix is to treat fungal AND bacteria infections, am I correct in assuming Melafix should not be nessarry? Or is there benefits to using both products together?
Answer by ChewyJul 09, 2019
You can use just the API Pimafix to treat the fungal and bacterial infections. If the bacteria and fungal infections persists this combination is in fact recommended in treating the stubborn infections. Use each medication at the recommended dose. There is no need to reduce the dose when using both of them.

What is the dosage for ponds?
Answer by ChewyApr 12, 2018
You should add 5ml of API Pimafix per 10 U.S. gallons of water.

if u were wondering if this does work or if it doesnt, here is my respond. yes, it does work. I noticed some white patches on my Fish, but I treated them with the CORRECT dose and In about 2-3 days they were all healthy no white spots or any fungal infections on them. Also If you're wondering what brand is best, in my opinion it's API. I have been using their products for a year now and they always work, which is why I always use API. only other brand behind it is prolly Tetra since their products are pretty good but my opinion API are best.

API Fish Care is Number One

I have been using API fish care products for over five years now and they are top quality. Not only do you get a superior product, you also can contact API customer support and they help answer questions and diagnose potential problems. (It is like have urgent care hot line for your fish.). My blood parrots of seven years picked up a fin fungus and API customer support was able to help me identify the problem, treat the illness, and get my fish healthy again. (This wasn’t my first time receiving assistance from them.). Our fish have been with us a long time, super storm Sandy survivors and now Covid 19, and are part of the family. Also, you want to buy through Chewy. Not only are their prices lower, but they offer products in all size quantities which provides further savings. Then combine your order for over $49.99 and you get free shipping with most likely two day delivery from the day you order. Furthermore, Chewy customer service is helpful and always able to help you or address any issues. For example, Chewy was fast to help resolve a delivery error by the carrier that was not their fault. Both API and Chewy have my loyalty.

it helped, but didn't cure in a reasonable amount to time.

New Betta from the pet store infected one of my tanks with a bacterial infection. The medication helped but didn;t cure the infection in a reasonavle amount of time - it has taken several 7day treatments to stay ahead of the infection.

Pimafix one of my koi fish doctors

All natural- no man-made chemicals!

Simply put- it works. If your fish look sick then treat your tank (pond in my case) by putting this in the water at recommended dosages. Follow the instructions and voila! Good for general issues. I use it (with Melafix) when my fish look stressed to stop an infection before it gets started or worse.

It does the job.

It works when used in conjunction with Melafix for minor fungal or bacterial infections. Carbon MUST be removed. It goes quick with a 150 gallon tank.

Works Fast!!!

I used it with melodic by the next day my fish looked better and his fins and everything is regrowing. Got a couple of new fish off offer up that we’re sick and within a day I saw the difference as well. Great product and great company. May be pricey at stores but with chewy you save a couple of bucks and it works!!
