Yes bigger pond equals bigger filter. Im looking for something that maybe is low profile ex. partially in ground or something like that. I checked out your filter deal. Have you worked out all the bugs yet? I have 2 plastic 55 gal drums with lids which use screw on lid rings to seal them,,,,just in case i would need to utilize them for some part of a filter system. Oh ya, i also have 4 cubic feet of bio bead material.
