What you are seeing in, and on top of the basket is a plastic mesh needlepoint canvas. The holes in the plant basket are too big for the clay litter so I lined them with this material.
The baskets just won't be practical for smaller tanks unless you have a sump. I'm not liking the space they take up in the 110g stock tank and I'm thinking of making a sump for them.
The filter was a bit outside the Novak box, but I had the materials and the idea so it only cost me very little in kitty litter and Flourite Red. The trick (if there is one) is to just trickle water through it. It's hard to say if anoxic bacteria develops there as maybe there's too much O2. But worse case, all that clay litter provides a lot of surface area for BB.
I think the plenum idea is a good one using an Under Gravel Filter covered with landscape fabric and a sand substrate. Again, the 'trick' is to only use enough air (or other means) to move just a little water through the system (Unlike the normal flow of UGF).
After several months, I thought my filter was keeping nitrates down on my 60g, but the baskets weren't doing much in the 110g stock tank (but as I mentioned, the stock tank has a LOT of well fed fish!)
Tank On, Mike-

What came first, the chicken or the egg. It was the egg, but not the egg from a chicken.
