A plenum was a void underneath the sand bed - initially an uplift was used with a power head to keep water running through, then you remove that and let the water under the bed become anoxic, so you get Nitrate reducing bacteria… That’s the theory, at least. Tried one once, never again.I thought the ol timers called that a "plenum filter" in salt water
Or was that something else?
