eheim substrat pro how much do i need?

[lads13]

would 5Lt be enough for 600lt in a wet dry filter?
thanks for your replies

in a sump or wetdry i would go with scrubbies or bio balls. a lot cheaper than sub pro and just as affective.

I have 12L in my sump. I had the E.Pro in a 2250 and that was rated for a 265g. My tank is 210g, 20g in the sump=230g. I have perfect parameters with the sump as i did with the 2250.
