"The Hiatt TBPC was used because of its large surface area per cu. ft. for a nitrifying bacteria platform. When used in conjunction with the RIght Now! bacteria, nitrates are converted to nitrogen gas and eliminated from the system. This has eliminated the need for constant water changes in order to reduce nitrates."
Is this possible? Do you know how it is that the nitrates are turned into nitrogen, which is a inert harmless gas?
There are bacteria that in the absence of O2 use nitrAtes to "breath". Do a search on "nitrate reactors" (I think that's what they're called). It's basically a extremely long length of tube or pipe that the water flows though and gets colonized with bacteria. As the water flows through the pipe the O2 is used up by the bacteria towards the inlet forcing the bacteria further down to use the nitrAtes. I imagine the pipe/tube would have to have some sort of media inside to give the bacteria more surface area to attach to than just the walls. And it would have to be kept in the dark to keep algae from growing in there and producing O2.
