+1 what are you going to be using for substrate?
Will you using pre filters to swap out the active substrates? What substrates will you be using?
Will you be using basically trial and error and constant testing to see what amount of substrate will last how long?
Are the red things on the left UGF connectors or are they blockers for the holes?
