Diving through species care sheets & parameters…
An older filtration style consisting of a slotted plastic plate beneath the gravel substrate, connected to vertical uplift tubes powered by air bubbles or powerheads.

Uses the gravel bed as a biological filtration surface while drawing water through the substrate.
Draws water down through the gravel bed, where nitrifying bacteria consume waste, and pushes the filtered water back up through the vertical tubes.
Requires regular, thorough gravel vacuuming to prevent detritus and fish waste from clogging the gravel bed and choking biological filtration.
