<\/p>\n

Existem muitos equ\u00edvocos sobre o fen\u00f3meno das algas pilosas nos lagos de carpas, e muitas pessoas at\u00e9 pensam que as algas pilosas s\u00e3o musgo, por isso aqui est\u00e1 o que sei sobre o problema que pode ajudar a compreender e a resolver as algas pilosas.<\/span><\/p>\n

1.<\/span><\/strong>Porque \u00e9 que h\u00e1 algas na piscina?<\/span><\/strong>
<\/span>Normalmente, \u00e9 devido a sistemas de filtragem imaturos, especialmente na primavera, quando as bact\u00e9rias ben\u00e9ficas est\u00e3o inactivas e n\u00e3o come\u00e7aram a trabalhar, que as algas pilosas crescem a um ritmo alarmante. Ent\u00e3o, um sistema de filtragem maduro significa que as algas pilosas n\u00e3o v\u00e3o aparecer? A resposta \u00e9 n\u00e3o. O crescimento de algas pilosas pode ocorrer em sistemas de filtra\u00e7\u00e3o maduros, mas por raz\u00f5es muito diferentes, muitas vezes devido \u00e0 sobrecarga de nutrientes.<\/span><\/p>\n

<\/span>2.<\/span><\/strong>\u00c9 poss\u00edvel utilizar<\/span><\/strong>uv<\/span><\/strong>A luz mata-os?<\/span><\/strong>
<\/span>N\u00e3o \u00e9 poss\u00edvel. A irradia\u00e7\u00e3o UV mata as algas planct\u00f3nicas porque as algas s\u00e3o capazes de atravessar a<\/span>UV<\/span>Luz. As algas peludas est\u00e3o normalmente agarradas \u00e0 parede da piscina ou ao filtro, e a luz UV n\u00e3o \u00e9 eficaz.<\/span><\/p>\n

3.<\/span><\/strong>Quais s\u00e3o os nutrientes das algas peludas?<\/span><\/strong>
<\/span>Uma coisa que \u00e9 certa \u00e9 que os nutrientes para as algas peludas n\u00e3o s\u00e3o os nitratos, mas sim os fosfatos e o azoto. A melhor rela\u00e7\u00e3o de fosfato e azoto para as algas \u00e9<\/span>16:1<\/span>(i.e.)<\/span>Redfield<\/span>(Valor).<\/span><\/p>\n

<\/span>4.<\/span><\/strong>Quais s\u00e3o as causas do aumento do fosfato e do azoto nas massas de \u00e1gua?<\/span><\/strong>
<\/span>A mat\u00e9ria org\u00e2nica, como as lamas, as fezes dos peixes, as folhas ca\u00eddas, as ervas daninhas que invadem a piscina, os adubos, os alimentos para peixes e mesmo a \u00e1gua da torneira t\u00eam o potencial de aumentar o n\u00edvel de fosfato na \u00e1gua, enquanto o azoto est\u00e1 sempre presente na piscina. A chave para isto \u00e9 o fosfato (<\/span>PO4<\/span>), uma vez que \u00e9 necess\u00e1rio para o crescimento das c\u00e9lulas microbianas. Os microrganismos necessitam apenas de menos de<\/span>1ppm<\/span>(utilizado como express\u00e3o nominal)<\/span>PO4<\/span>, em geral<\/span>PO4<\/span>menos de<\/span>5ppm<\/span>N\u00e3o surgir\u00e3o problemas graves de algas.<\/span><\/p>\n

.<\/span><\/strong>Como posso reduzir as algas peludas?<\/span><\/strong>
<\/span>inferior<\/span>PO4<\/span>\u00e9 a chave. Primeiro, medir o aqu\u00e1rio e a \u00e1gua da torneira no<\/span>PO4<\/span>se a \u00e1gua da torneira da<\/span>PO4<\/span>O n\u00edvel \u00e9 muito baixo (<\/span>1ppm<\/span>ou menos), isso pode ser resolvido mudando a \u00e1gua. Mudar a \u00e1gua todos os dias<\/span>30<\/span>por cento, uma semana mais tarde<\/span>70%<\/span>As algas pilosas devem ter desaparecido. N\u00e3o se esque\u00e7a de verificar a bomba, pois algumas das algas podem estar a\u00ed presas.<\/span><\/p>\n

6.<\/span><\/strong>O que posso fazer se n\u00e3o conseguir reduzir os n\u00edveis de PO4 mudando a \u00e1gua?<\/span><\/strong>
<\/span>\u00c9 aqui que a palha de cevada ou o per\u00f3xido de hidrog\u00e9nio podem ser utilizados. Na filtra\u00e7\u00e3o ou nos tanques de peixes, a palha de cevada pode produzir pequenas doses de per\u00f3xido de hidrog\u00e9nio durante um longo per\u00edodo de tempo. Em compara\u00e7\u00e3o com os produtos qu\u00edmicos, a palha de cevada \u00e9 mais segura. Se tiver de utilizar per\u00f3xido de hidrog\u00e9nio, certifique-se de que possui bons conhecimentos de qu\u00edmica e o equipamento de dosagem necess\u00e1rio.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
