        1. Estrat\u00e9gia de oxigena\u00e7\u00e3o do equipamento<\/span>\n
            \n
          • Ligar o oxigenador durante 2-3 horas \u00e0 tarde, em dias de sol, para promover a troca das massas de \u00e1gua superiores e inferiores e libertar os gases nocivos do fundo.<\/span><\/li>\n
          • Adoptando discos de aera\u00e7\u00e3o microporosos ou nano pedras de ar, o baixo ru\u00eddo e o elevado efeito de oxig\u00e9nio dissolvido \u00e9 conseguido atrav\u00e9s da liga\u00e7\u00e3o da bomba de circula\u00e7\u00e3o do sistema de filtra\u00e7\u00e3o.<\/span><\/li>\n

            • Polvilhe bact\u00e9rias fotossint\u00e9ticas ou solu\u00e7\u00e3o bacteriana EM para inibir o crescimento excessivo de algas e promover a produ\u00e7\u00e3o de oxig\u00e9nio por microrganismos ben\u00e9ficos.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

                  • Ao mudar a \u00e1gua em caso de emerg\u00eancia, seguir o princ\u00edpio \"pouca quantidade, muitas vezes\" (uma \u00fanica mudan\u00e7a de \u00e1gua \u2264 20%), para evitar flutua\u00e7\u00f5es dr\u00e1sticas da temperatura da \u00e1gua que provoquem stress nos peixes.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
