All I was stating that if you use the blue pad or any pad in the top tray , your filter will plug prematurely, slowing down flow and o2 to the media. Fluval doesn't even recommend matting until the middle or lower basket .. I'm more interested in clean water going to the aquarium than keeping my bio media clean.. besides eheim pro media is spherical and resists clogging better than SC matrix.
