Was JBL Nedol effective? I don’t notice any effect.
The course of every treatment is unique. Depending on the species (Camallanus or not Camallanus), up to 4 treatments are required, as described in the instructions.
Ideally, there will no longer be any signs on the fish after the first treatment. However, the treatment must be carried out until it is completely finished. That is the only way to fully eliminate the larvae which are hatched from the eggs.
In cases of more severe infestation, the fish may take longer to shake all the parasites off of their bodies.
An absence of effect is frequently traced to the circumstance that potential intolerances e.g. in shrimp did not occur.
In the instructions for use, we point out that JBL Nedol should not be used with shrimp: Not to be used in invertebrates (corals, snails, shell fish, shrimp etc.) in fresh water or salt water.” This passage indicates that intolerances may occur. This, though, does not lead to the conclusion that the product was ineffective if shrimp and planarians survived.
As JBL is aware of intolerances in some species, we are unable to recommend use in connection with these groups. It is not always immediately possible to recognise whether a treatment was successful or not. Please follow the instructions for use closely.
