Ned,
I was in today and picked up the Msobo (all of them.....

)and some other guys. Just wanted to relate to others about the conversion of the quickfilter. I used the black foam that I got, I think it is for a pond filter. Cut one sheet in half. Took the clear plastic core from the quickfilter cartridge and wrapped both halves of the cut black foam around the clear plastic insert. Placed that into the black halves of the quickfilter, attached and it is working great. Now all I will have to do is rinse in cold water and put back on the power head when I change the water.
