Ammonia cleaning solutions, such as those used for household cleaning or industrial purposes, can contain high levels of ammonia that can be harmful or even fatal to fish. If these cleaning solutions are accidentally spilled into water bodies or come into contact with fish in any way, it can have severe consequences.
Therefore, it is crucial to keep ammonia cleaning solutions away from aquariums and any water bodies where fish may be present. Proper handling, storage, and disposal of these cleaning products are essential to prevent potential harm to fish and aquatic ecosystems.
