Where it appears
Chitosan appears on the ParaShield and BacterShield active panels. Fritz lists a different set of oils around it in each formulation.
What cannot be inferred
The product pages do not establish the polymer grade or fraction. A film-forming description is not a test of a formulation in a particular aquarium.
What to capture
Preserve the brand and complete companion ingredient panel, not only the shared polymer name.
