Em particular, o res\u00edduo alcalino das piscinas de bet\u00e3o, o \"efeito de fluxo curto\" dos sistemas de filtra\u00e7\u00e3o e a inativa\u00e7\u00e3o a baixa temperatura das bact\u00e9rias nitrificantes s\u00e3o os tr\u00eas assassinos invis\u00edveis mais facilmente ignorados pelos principiantes.
