Submerged or trickle for bio media?

[CharlieTuna]

I'm going to have glass cut today for my DIY sump, I'm using a 40g breeder for the sump, 210g display, freshwater. Should I set up the sump so that the bio media (about 4L of Seachem pond matrix) is completely submerged or trickle style like a standard wet dry? I will be using a piece of Poret foam at the entry of the sump for mechanical and a little bit of additional bio filtration. In addition to the sump, I will be using two Ocean Clear canister filters.

Curious what your bio load is and how much matrix you are using?

Mine trickles over 10 gal of bioballs. I then packed the "wet" part of the filter with japanese pond mat. It's great stuff
