Is undergravel filter good for planted tank?

How does an undergravel filter work with a powerhead?
The undergravel filter plate is covered with aquarium gravel. The aquarium water is drawn up the lift tube along with bubbles from an air stone at the bottom or by a small motor, called a powerhead, at the top. This pulls water from under the plate, which in turn draws water down through the gravel.
Can I use an undergravel filter with live plants?
About U/G Filters and Live Plants: Rooted aquarium plants and undergravel filter plates are often cited as mutually incompatible, with various notions offered to explain why plants don’t do well with water circulating too much about their root structures.
Can you use an undergravel filter with sand?
Sand and UGFs don’t mix. You can not use sand and UGF and you can not have UGF with plants. People that use UGF generally use them in rock tanks with reverse flow pumps to push the gunk UP and then other filters to remove what is pushed up. They do not filter well enough used alone.
What’s wrong with Undergravel filters?
1 If a UGF is not maintained properly the media builds up an accumulation of detritus and other organic matter, which in turn contributes to a build-up of high nitrate levels. Another factor is that underneath the filter plate, dead spots can form.
What are the benefits of an undergravel filter?
Undergravels don’t do a great job at removing debris (mechanical filtration) or purifying the water (chemical filtration), and their main benefit is to draw debris into the substrate where they break down biologically.
How does an uplift tube work?
Uplift tubes, like those on air-driven sponge filters, are attached to the grid. The filters are powered by air pumps, or powerheads, and draw water down through the gravel and into the uplift tubes to be returned to the aquarium. The gravel acts as the filter media and this is where the bacterial colony lives.
How much gravel do I need for an undergravel filter?
If the gravel size is too small, or if you add sand to it, it will drop down and clog the slits, restricting the flow of water through the filter bed. As a general rule of thumb allow about 10lb of gravel per sq ft or roughly 45 kg per m2.
