Need info on filtration under gravel

[Paulie069]

New lg tank. Herd of a filtration system that goes under the gravel in tank that does good job of cleaning up poop n leftover food particles. Are they expensive and can I use other filtration systems with it

I wouldn't do that, it's old school. Can lead to buildup of bad nutrient levels over time. I had mine like that back in the 70s. You could use air stones or power heads the fit inside the uptubes to draw water thru the gravel & that caused the uneaten food & poop to accumulate under the plastic filter sheets.
Edit:
Here's some info.

Is an Undergravel Filter the Right Choice for My Tank?

You might be talking about the berlin method. At least i think that is what its called.

Thanks for input but I’ve decided not to go that route

I forget maybe it was plenum but it was different than under gravel but either way there are better ways now. Good choice not to go that way.

If you'd like to read up on the plenum method, there's an excellent write up and research by Bob Goemans on saltcorner.com. Not recommending it for your display, although I'm very likely to setup a secondary tank using the Jaubert Plenum method, but that's just my curiosity. My display is simple, berlin all the way. Still a fascinating read and I always enjoy learning about the history of the hobby. Oh, there's some Dr. Jean Jaubert vids from conferences on YouTube. He invented the methodology.

FYI
It will work for a fuge. Where you want a lot of critters and bacteria to be under the gravel. If you do that, you need to do it in reverse. Where you pump water under and it pushes stuff up and out of the gravel.
Paul B runs one in his tank and it has been up for a bizzillon years

Where is @Paul B when you need him. He's been running under gravel since Adam and Eve! Hopefully he'll check in and explain, but I believe he runs it in reverse.
