Hola Joaquin, lo cierto es que el rango de aplicación a variado con los años y es un poco lioso, actualmente la aplicación se debe realizar de la siguiente manera; 0,1 g/L si se aplica con el resto de la gama Grotek y 1g/6L (0,6/L) si se aplica de forma individual. Un saludo.

En el video dice 0,6g por cada litro de agua y en las indicaciones escritas 1,5g cada 10 litros, alguien me lo puede aclarar?gracias un saludo

Hay que probarlo pero la EC no sube mucho que es lo bueno y es un bote pequeño que equivale a otro de 2l en líquido y ahorras espacio
