API MELAFIX heals bacterial infections such as fin & tail rot, eye cloud, popeye, body slime, and mouth fungus.

My ponds has salt in it 2 days ago can I add melafix in? Is it safe for my koi?

Answer by ChewyFeb 27, 2021
API MELAFIX will work in both freshwater and saltwater aquariums. However, we recommend turning off protein skimmers and UV sterilizers when using it. If you have carbon in your filter, this should be removed before using Melafix. API MELAFIX is safe for delicate fish species, all marine fish, and reef aquariums.

Does this cure pop eye.

Answer by ChewyOct 23, 2020
Melafix effectively treats fish diseases like tail and fin rot, eye cloud and mouth fungus.

works great in a 600gal. pond

I am in the process of deleting some fish as suggested by a local pond store. This product keeps them alive and feeding well with fin root.
