How does Pond Wizard improve the health and disease resistance of the fish?
The reason why a fish succumbs to a bacterial or fungal disease is the bacteria or fungi that form the disease have become predominant. If the pond system were kept in better balance and the disease microbes had greater competition, then they would not become predominant and form the disease. The micro-organisms in Pond Wizard are present in huge numbers and in a number of different species. They do not remove the disease forming species but compete with them for food and space and keep their numbers down so they do not take over.
