I missed something. UGF's are generally not good for planted tanks
because roots clog them up. Some people have also said that the roots get
down into the open water and rot off. I'm not sure how much I agree with
that part, but I do know from experience that they will clog with plant
roots if you don't pull up the plants every month and cut the roots.

About my tanks:
29 gallon tank (110 Litters).
-I have 5 glolights, 2 neons and 3 black neons, 3 skirt tetras, 2
home-raised mollies, 1 home raised guppy, 4 Otocinclus catfish, 2 albino and
3 juli cories, 1 pleco, one female betta, and 1 paradise gourami. I do not
recommend this setup for starting a new tank!
-Plants: "hardy" aponongetons, red tiger lotus, banana plants, java ferns,
hornwort, and amazon swords.
-Single 20 watt 5000K light, plain gravel, Regent 30-60 power filter.
Ammonia 0ppm, Nitrite 0ppm, Nitrate 30ppm, KH 2°, pH 6.4.
10 gallon tank (38 Liters).
-Multiple bettas, all born in June.
-Plants: hornwort, red tiger lotus, amazon sword
-2 10 watt 6500K mini fluorescent lights, plain gravel in spots, sponge
I can't find the link, but the article said: "You are stuck with the
UGF unless you totally breakdown your tank. All the junk that has
built up under the filter plate will become a toxic bed if you stop
using the UGF." I hope that explains it a little bit better then
before. UGFs are real good for planted aquariums from what I have
learned, but better for tanks less then 55 gal. I had a 30 gal. tank
about 25 years ago that had a UGF, and you could see all the junk
sitting under the plastic plates, so I figure it would become toxic
to the fish if not removed.
