| Alright...here's a question, and maybe I'm just missing something....with the bigger sized substrate, it's possible that some waste matter would travel down into the plenum space. Now, my question is - if these "wastes" would settle on the very bottom and NOT get taken out with the water (when it came time to remove it) then what would occur? Would there be any way to agitate the settled material in order to take it out with the water, would it be fine sitting down there, or would it create problems once the water was removed? Maybe I am way off base?
