I agree that aiming soley at a small footprint is not good, but I make the point that it is possible to get serious solids removal down to fines in a small footprint because that's what a lot of people want.

This doesn't alter the wattage, as the flow is the same. I will be taking the water from the screens and staticK and pushing it thru a large TT.

Bekko, sand gravel beds collect the muck in tiny crevices where they are subject to compressive water flow passing thru them, which boosts nitrates and disolved organics, and can lead to tracking.

In static K, the structure is so open that water isn't forced thru crevices, but flows a tortuous route where the solids and fines are deposited in dead spots while the water flows by.

Plus, fluidising the K to clean it is easier and more thorough than trying to fluidise sand gravel as the K is neutral to slightly positive buoyancy.
