O amónio e a amónia originam-se principalmente a partir dos excrementos dos peixes. Dependendo do valor do pH, o amónio transforma-se em amónia e vice-versa. Enquanto o amónio é, em grande parte, inofensivo, a amónia é tóxica para os peixes. Com o sera teste de NH4/NH3 determina- se a concentração de ambos (com a ajuda do valor de pH, na tabela que acompanha o teste pode ler o valor real de amónia). Em caso de perigo, o sera toxivec (água doce), ou o sera pond toxivec (no lago), são de grande utilidade. sera bio nitrivec (água doce), sera marin bio reefclear (água salgada) ou sera pond bio nitrivec (lago) evitam a acumulação destas substâncias a longo prazo. É suficiente para aproximadamente 60 leituras.
