Thanks, Gene! It's all becoming clear to me now!

The two stage protein skimmer with ozone injection followed by a reaction chamber is probably just to make sure to utilize all the ozone so that residue ozone does not make it into the display, much like how a two stage calcium reactor is more effecient at using all the CO2 you pump into it.

The stylized diagram has the water going through a protein skimmer AND a "aeration chamber".

This would be rather simple. You have your standard protein skimmer. The water that exits it, which may contain residual ozone, is then dumped over a small trickle filter. This would be something simple like a section of PVC pipe containing bioballs. If the top and bottom of this chamber was exposed to air, that would be all you would need. But if the bottom were submerged, pumping air into it would be necessary. This is just another little reaction chamber to make sure to use all the ozone. But regardless, I would still have the water that exited this chamber run through some activated carbon.

Thanks again, Steven!
