Sigh. Again with the UGF-bashing. I have half-a-dozen tanks and have been
keeping planted tanks for over twenty-five years. Practically every single
one has or has had an undergravel filter. There is no problem with using
UGF's.

I have a decent sized tank (4x3x2 ft) with only 4 plants and five small
fish
in it, all was going well until all of a sudden the plants with broad
leafs
started going brown and dieing Why??. I have a power head filter and
two
under gravel filters. the fish are fine and the two plants that aren't
broad leafed are fine


Growing plant in tanks with under gravel filters has never worked for
me....they generally don't like the flow of oxygenated water over their
roots.
