here is my modified design...i changed the baffles to be the same height and made one layer of filtration media for each type (mechanical, chemical, biological).
i was gonna try BioMate balls for all 3 levels of filtration...they have foam filled, carbon filled, and ceramic filled ones that i was gonna separate with eggcrate. has anyone used BioMate balls before?
oh by the way theres a typo in my drawing...the blue balls are biological...i put yellow in there twice for mechanical...it goes yellow=mech, black=chem, blue=bio
