Pull the flex hose off the the surface skimmers from Hagen, Tom or Fluval, and you have the essential construct for this mod. I drilled a hole in one segment of the Eheim Installation Set 1, using a 1/2" drill bit, and sanded the hole to its final ø ID (just enough to press fit the skimmer nipple). I used old segments to fiddle with; that's why the the ones in the photos look gray/white. These skimmers have a collector that floats with the water level. So I opted to locate the hole, a bit lower on the segment I intended to drill. Locate the skimmer too high, and the slotted collector will be too high to operate. I inserted the skimmer nipple, about 1/8", into the hole, and tacked the arrangement to my tank glass with suction cups. The water movement, generated by the canister, past the nipple will form a venturi, and pull water through the skimmer. You will get more draw through the skimmer by plumbing it according to instructions. Had this arrangement been ineffective, I would've used the tee configuration (which is what I was trying to avoid). edit: sp
