Xport NO3 Dimpled Brick

looking to hear what other folks have to say: i recently put in a Xport No3 brick into my biocube 32.
i keep hearing that this brick can produce anaerobic condition and assist in denitrification. And i dont understand....
where in a reef tank can there be anaerobic conditions. In order for something to be anaerobic there needs to be
no available oxygen. that will include dissolved oxygen and chemically bond oxygen. ex) Nitrate NO3 is a form of
chemically bond oxygen. And there is plenty of dissolved oxygen in the tank just from the cascading created in the
back chambers. heterotrophic bacteria denitrify... and they only denitrify in anoxic conditions. Anoxic: chemically bond
oxygen but no dissolved oxygen. how in the heck does this brick work?

Theoretically the oxygen can be striped in the first 1/4 inch of the block. Also the NO3 block has sulfur added which helps the right kind of bacteria. The no3 blocks are supposed to be replaced over time as the sulfur is depleted.

Thanks for the response.
