There is also some evidence that some species of these parasites are resistant to some regularly used treatments.

Successful treatment depends upon ingredients which can penetrate the mucus and reach the parasites.

B-D-S is a fluke treatment providing a tried and tested formulation which treats both skin and gill flukes as well as bacterial disease such as fin rot, tail rot and ulcers.

Please note: The warnings on the label and handle the product with care.

The correct dose of B-D-S does not affect the filter bacteria or plants and persists in the water long enough to destroy the various stages of parasite which may otherwise remain to re-infect treated fish.
