When is it safe to enter pond to clean or arrange plants after treating with pimafix/melafix?

Answer by Chewy • Sep 23, 2019
This treatment is intended to be used every 24 hours for the course of 7 days. Because API only conducts their tests with fish, it's recommended to reach out to your doctor to see how soon you are able to re-enter the pond. The active ingredient in this treatment is Pimenta racemosa.

I have a large fancy goldfish out front in our SMALL pond. He had the bloat thing for two years. Used pimafix and three days later, HE IS SWIMMING AGAIN! Playing with his buddy again, they’re both about five inches long. He’s is eating again. Sinking food only! Thank you!

Crossing my fingers.

We've lost 8 large koi recently after getting some bad goldfish which were quarantined. This seems to be working along with melafix and water changes.

Did not work

I lost a koi to fin rot and treated with Melafix and Pimafix ( just in case there were parasites too.) 4 days into treatment I lose a second koi. No fin rot. Water

I lost a koi to fin rot and treated with Melafix and Pimafix ( just in case there were parasites too.) 4 days into treatment I lose a second koi. No fin rot. Water parameters are all as they should be. I can only figure parasites. Waited 1 week for chemicals to dissipate. Treated with HKF Praziquantel and Proform C 3 days later everyone is eating and back to themself for a lot less money. Save your money, worry, and time.
