I use a internal power filter 800 l/h

Oh, then I guess you're not using a canister filter, either?

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?
If the UGF is working properly, the waste ends up in the water column
(converted to nitrate). That's not bad in and of itself, but most
planted
tank
keepers like more control. If we want something in the water column, we
put it
in the water. If we want something in the gravel, we put it in the
gravel.
