Undergravel Filtration w/ planted tank

Hey I was just wondering if anyone here has ever tried planting a tank with gravel filtration. The reason I ask is I have a tank thats plumbed with filtration that draws from the bottom of the tank and I wanted to plant this tank and was wondering if the plants with substrate and all could co-exist with the undergravel filtration. Thanks

Not recommended. The roots will grow into the undergravel filter. More trouble than it's worth.

is there any other problem than that ,if you plan on keeping the tank for a while
it seems like a good thing for a shrimp tanks and if your only growing the plants in gravel wont it help bring the ferts too the roots ?

It's best to have a deep substrate with planted tanks. UGF's require a shallow substrate. If you use a thick substrate, there's a possibility that you will have gaps in the flow through the gravel.

Also, UGF's need to be maintained properly. Thorough gravel vacs need to be performed. Otherwise, detritus collects over time underneath the UGF plates. Have you seen your filter hose? Imagine that stuff underneath the UGF plates. All the detritus that collects will eventually cause dead spots and gas pockets.

As mentioned, the roots could get attached to the UGF plates and may cause the UGF to shift/move when removing/rearranging plants.

Clean gravel is inert gravel, so don't do it.

I am running an UGF that I constructed w/ 1/2 inch diameter thin walled PVC pipe. My eheim 2028 intakes thru the gravel bed and is returned normally. So far I'm very happy w/ things. About 2-6 inches of flourite sits on to of the pipes which were first covered by screening.
