What kind of tank is this? Heavily planted? Heavy bio load? You need to plan for what you're trying to filter out of the water. On my heavily planted tank, it's all mechanical; tons of coarse pads and floss. On the shrimp tank, one is packed with Substrat, the other with floss and purigen. Two different tanks, two different approaches to filtration...
Eheim Filter substrate suggestions
So I have an Eheim 2217 on my 46G. I've not had any issues with it but since I'm clumsy I have managed to spill the SubstratPro bio-filter media (that came with the filter originally) a few times and being paranoid about cleaning supplies on my floor I've always thrown out stuff that's spilled.
Anyway, since i'm probably going to have to buy some filter media to replace it I was thinking of changing it up and wanted suggestions. Here's the current layout:
Top
Substrat Pro

Has anyone used Eheim Lav? Is there any advantage to this product? Here's the setup I'm thinking, suggestions appreciated:
Top
Micron Filter
Purigen x 100mL in The Bag

Oh yeah I guess I should have mentioned. It's pretty heavily planted, very low bioload right now (4 fish, a few shrimp).
What you've said makes sense about mechanical filtration only (and you probably pick up some ancillary biofiltration anyway even with that setup if you have minimal bioload. I might consider that if I don't add more shrimp to the tank...thanks!
How do you feel about Purigen, do you see any difference in water quality with it? I've heard good things but never tried it.

I was given some Eheim Lav and never used it because well, i never change my biomedia. Personally I wouldn't buy it though because they are such tiny pieces with very little surface area. You will need to buy a lot and its not exactly cheap. I would suggest ceramic bio-rings by fluval or rena as an alternative to the Substrat Pro.

This is assuming your flow is from the bottom to the top

Purigen is AMAZING in its ability to clear waters. I had a newly dirted tank, wasn't doing WC's on it to help the cycle, and the purigen kept it crystal clear the whole time. Not to mention it's reusable, which is a big plus...How do you feel about Purigen, do you see any difference in water quality with it? I've heard good things but never tried it.
Hmm thanks for the suggestions all. Ended up pulling the trigger on the Purigen since the clear water thing sounds pretty great and it was inexpensive. Glad to hear the opinion on the Lav, I think I'll stick to the Substrat Pro since it's free (in place) and cycled up. I'm hesitant to go to that much filter floss livingword26 since I anticipate increasing the bioload somewhat and I HATE changing gunked up filters...so I think this'll be the setup:

Micron Filter (or will move the Purigen to the top and fill this chamber's bottom with Substrat as well)
Purigen x 100mL in The Bag

Anyone used the micron filters? I have heard great things about water quality but I'm wondering if I need it if the Purigen already does a good job of polishing?

Yea, everyone does it different. I gotta say though, that gunk has to be somewhere.
If you want to do mechanical filtration only; you could just fill it up with coarse filter pads (art no. 2616171) except for the top layer where you have a fine pad (art no. 2616175) and the Purigen. Another way is to add a bottom layer of the Eheim mech and then coarse pads in the middle topped by the fine pad and Purigen.
A cheaper route would be to use a big wad of filter floss between the coarse pad and the fine pad with the Purigen.

I set my first filter up like the third picture above, only with one less blue pad and more floss on top. I've found that the blue pads hardly get dirty at all, while the floss gets filthy in a hurry. Unless you have tons of visible chunks of plants/poop floating around, I'd recommend maybe 3 blue pads, the rest floss.
