A question that still remains with me is: If the water is flowing over the top of the sand, once the sand is saturated how does water diffuse down into the depth of the sand bed/bucket? It seems it would just run over the top. How then does denitirification take place? This is a very different then the method of large square footage and lots of sand bed critters to keep the bed active.
