Ray;

No pics, I got no camera! The canister is really simple. It's a 4" diameter tube, 12" long. On one end i just cemented a bottom, and mounted a threaded adapter in it to hold a hose barb. That's the outlet. I also put some eggcrate in that end to hold a piece of fiberglass filter, to keep the carbon in place. On the other end I cemented a flange; all it is is a square piece of acrylic, then I flush trimmed out the middle inside the tube. Then there's a lid, which is the same size square, with another threaded adapter mounted, for input. A few holes for nylon thumbscrews, some rubber for a gasket, some "legs" mounted to the bottom piece so I could have it stand up vertical, and it was finished. I used a mag 7 to push water through it; probably a mag 5 would be better, cause they say that it's a little better to have slower flow through carbon for increased contact time.

I did this out of extruded, because I only intended to use it for this treatment. But, after seeing the new clarity of my water, I'd consider running some carbon through it every couple of months for a day or two.
