Hey Guys,

Thanks for all the info.

I still have one question - Using a UGF pulls water through the gravel and
back to the top of the tank.
because of this the gravel becomes a mechanical filter trapping what ever
gets pushed through it (plant matter and fish waste). Isn't that good for
the plants when it comes to feeding?

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

any suggestions would be greatly appreciated

thanks

Ben
