Hay una p\u00e1gina web alemana, Aquaristik ohne Geheimnisse<\/a> (acuarismo sin secretos), con abundante informaci\u00f3n de alto inter\u00e9s. Es una referencia para muchos temas en los foros disqueros alemanes. Y tambi\u00e9n habla del lodo en el acuario.<\/p>\n\n\n\n

Quiero compartir lo m\u00e1s relevante de una publicaci\u00f3n del Dr. Gerd Kassebeer, de 1997 sobre el lodo en el acuario.<\/p>\n\n\n\n

La historia del viejo lodo en el acuario<\/h3>\n\n\n\n

En  1906 apareci\u00f3 la 3a edici\u00f3n del \u00abManual para aficionados a acuarios y terrarios\u00bb del Dr. E. Zernecke. En la secci\u00f3n \u00abEl mantenimiento del acuario\u00bb dice en la p\u00e1gina 398 entre otras cosas:<\/p>\n\n\n\n

\"lodo<\/figure><\/div>\n\n\n\n

\u00abEn un acuario bien instalado y plantado, el agua debe mantenerse transparente y clara, incluso tras a\u00f1os de uso sin renovaci\u00f3n.<\/cite>\u00ab<\/p>\n\n\n\n

Esta cita y otras parecidas de la misma \u00e9poca demuestran que nuestros antepasados no cambiaban agua. Estaban convencidos de que el agua vieja era lo mejor para su acuario. En otra parte del libro, se enaltece la funci\u00f3n biol\u00f3gica del la capa de lodo que se forma. Esto parece una contradicci\u00f3n con nuestras experiencias actuales. Hoy en d\u00eda, los cambios de agua semanales y el sifonado son rutinas habituales de la mayor\u00eda de los acuaristas. No hacerlo produce mala conciencia. Yo tambi\u00e9n he cambiado agua durante a\u00f1os. Estaba convencido de hacer lo correcto. De todas formas crec\u00eda mi sospecha de que el agua vieja de nuestros antepasados s\u00ed podr\u00eda tener sentido biol\u00f3gico. Para averiguarlo empec\u00e9 a investigar.<\/p>\n\n\n\n

El primer experimento fue en un acuario de 15 litros. Ten\u00eda plantas de superficie y un grupo de cipr\u00ednidos (Leucaspius delineatus), un filtro interno Tetra Brillant de dos esponjas con una bomba de aire y mucha luz. Los peces estaban felices, recibiendo a diario alimento vivo. Sobre la arena se form\u00f3 una gruesa capa de lodo. Las esponjas se atascaban de vez en cuando y con un poco de presi\u00f3n se desatascaban. El agua evaporada se repon\u00eda con agua del grifo. Las plantas flotantes formaron una buena capa y luego dejaron de crecer, pero no se podaron.<\/p>\n\n\n\n

Semanalmente med\u00eda pH y dureza. Primero el pH cay\u00f3 en 3 meses de 7,5 a 6, volvi\u00f3 a subir a 7 tras 3 meses m\u00e1s. As\u00ed permaneci\u00f3 hasta la interrupci\u00f3n del experimento. Por otro lado, la dureza subi\u00f3 de 10\u00b0 GH hasta 20\u00b0 GH y no se movi\u00f3 m\u00e1s. Despu\u00e9s de un a\u00f1o par\u00e9 el experimento porque los par\u00e1metros no cambiaban m\u00e1s.<\/p>\n\n\n\n

Resultado<\/h3>\n\n\n\n

El resultado del primer experimento con agua vieja me sorprendi\u00f3 mucho. Habr\u00eda esperado un desplome del pH o un endurecimiento extremo. Durante mucho a\u00f1os no entend\u00eda lo que hab\u00eda pasado. Consult\u00e9 a expertos, qu\u00edmicos, microbi\u00f3logos, adquir\u00ed mucha literatura t\u00e9cnica. Buscaba una explicaci\u00f3n pero inicialmente sin \u00e9xito.<\/p>\n\n\n\n

Siguieron m\u00e1s experimentos. Cada vez midiendo m\u00e1s par\u00e1metros. Surgieron montones de datos. Comenc\u00e9 a interesarme por la desnitrificaci\u00f3n. Aqu\u00ed parec\u00eda estar la soluci\u00f3n al misterio. Me iba acercando. Finalmente la encontr\u00e9 en otra parte. En las depuradoras de agua. La respuesta no est\u00e1 en el agua vieja, est\u00e1 en las propiedades del lodo!<\/p>\n\n\n\n
