All-natural koi pond bacteria treatment. Aeromonas and Pseudomonas are deadly bacteria that live in every pond, causing life threatening infections such as ulcers, fin rot, tail rot and more. Aeromonas and Pseudomonas attack koi and garden pond fish when they are stressed, causing many thousands of fish deaths each year. Aqua MedZyme Dry Concentrate reduces the risk. Here's how:
