i get what you're saying bob. the smaller the grain size, the more sand you have in a cubic inch, the more surface area there is, the more critters can live on the sand. the bags of SWC sand jon brought in has some absurd number on it, the exact space available, but it makes sense i guess. the same concept applies to bioballs.
i guess the one thing i can't figure out is, where is the sulphur from the hydrogen sulphide coming from? it's not organic waste, it's not in the water, it's not in the sand... or am i missing something. however it does make sense, that if you're going to have anoxic (is that the word) areas in the sand bed, then there has to be some other gas down there, and H2S makes as much sense as any, i suppose.
