Aquarium treatments
Every record is a specific formulation in a specific market, because the same brand name can be reformulated or sold differently elsewhere. Blank cells mean the manufacturer has not addressed that group—not that it is safe.

FishyMag reports what manufacturers say, quoted and linked. It does not diagnose illness or recommend a treatment, and it never infers that a product is safe from the absence of a warning — where no statement exists, it says so.
Formulations change. Always read the label on the bottle in your hand, and contact the manufacturer if your tank contains anything valuable or unusual.
