Timmer,

Many plants do not do well with UGF's because people do not put enough
gravel on top of the filter plates. And UGF should have 1 1/2 inch to 2
inches of gravel on top of the plates, and RUGF need about 3 inches. Most
people do not want to put that much gravel in their tanks.

HTH

1 1/2 inch? When I first started fish keeping about 1 1/2 years ago,
I had a UGF. I had about 3" of gravel. Needless to say, it got very
smelly.

Then, under advice, I removed 2's of gravel, and it worked better.

Then under ingrid's advice, I removed the UGF, Binned the tank, bought
a 10g & filter. Things work very nicely.

I'm a filter convert. UGF's just don't seem to cut it in my tanks,
and I'm sure it was responsible for the death of my black moor.
