We didn't really feel the need to take pictures of this figuring everyone would be able to handle it by themselves but here are some photos of rez with 3 holes (and stop valves) in it and the bucket we are circulating with the system. In this case we're only using one but just imagine it as 8 of them all daisy chained together because the priniciple is exactly the same no matter what.

TIP: Buy those 1/2 inch stop valves in bulk.....you'll thank me later.

Afterthought: After drilling a third hole in the res it occurred to us that you really only need two of them (strictly speaking...an intake line and an outtake line) and the lower rez DOES come with two holes already. If you want to keep an eye on the water level you'll need 3 but can GET BY with the two already there.
