Lightbulb Multi-Media filter?

Here's an idea I've been toying with; I currently have a Magnum 350 Pro for my 75g, but I wanted to use the micron filter with it, and have a seperate filter setup for the chemical filtration. But I don't want to fiddle with pantyhose/bags/mixes/etc. - so I came up with this idea:

Basically, there are three compartments, the base, and the top. Each piece will have thumbscrews to hold them together around the perimeter flanges, but each one will be totally seperate so if one requires changing more or less often, it can be pulled out seperately, without having to totally disassemble the entire filter.

The left side shows the functional diagram, the center is a 3D view of an individual stage, and the right of course, is somewhat of a 3D view of the entire assembly. The entire piece will be constructed out of 1/4" acrylic. Each "stage" will have a perforated bottom, and an open top. If additional media types are desired, I can make additional stages, and just add them in.

The one thing I'm not entirely sure of - is what material can I use to seal between stages..? Is rubber acceptable? I can get 6" square x 1/16" thick pieces at the hardware store for $1 each, and cut them accordingly, but I wasn't sure if the rubber is harmful to the fish or not.

Any thoughts?

This is almost the exact same as the configuration of the Rena XP3. Nice, but you're reinventing the wheel. Also, you really wouldn't want to use this on a planted tank - you'd be taking out many of the nutrients that most of us put in. In fact, the plants in your tank should work as a chemical filter.

Well hell, and here I was thinking I came up with something nifty. LOL.

I do want to do something like this on my non-planted tank though.
