Does any one use a bio filter in there systems?
Or does it take out all of the nutients?
I'm just getting started and the only equipment I have is IBC 275 gal tanks and 55 gal drums.
I want to raise afew fish this fall and winter and then start my growing beds in the spring.
The spring plans include the purchase of a 40" steel shipping container and a home made green house as the future home for this project.
Thanks
Mike
