I'm trying to set up a 4x4x3.
I have a 40 gal sump and 60 gal acrylic tank sump.
Set up I'm thinking about.
Tank drains to 60 sump then to 40 sump then back to tank.
I usually just fill my sump with ceramic media. Debating if I should use all k1 for the 60 gal. But I never used k1 before. Watched a bunch of videos but never tried it.
