I got great replies from my last post. I have biowheels on my 90 gallon reef, and have never had a problem with nitrates. People commented that the filters trap junk and thus increasing the bioload. The rock traps debree as well. The plain truth is that bio wheels or bioballs produce no more nitrate than live rock or live sand does, and it is the live rock and live sand that converts the nitrate to gas. So who cares how the nitrate is produced if it gets taken care of by the live rock. I am still curious why the bio wheels and bioballs are still called nitrate factories in the reef tank enviroment when live rock does the same thing. I think the myth was started by people who don't understand the nitrogen cycle and wanted to sound cool with their fancy, and mutli billion dollar filter systems. And to the reply about deep sand beds converting nitrite to nitrate by oxygen depleted bacteria. The bacteria are low oxygen level bacteria. The nitrate converting bacteria that live in no oxygen are erobic ( I think That is how it is spelled ) And look like black patches. These will produce very toxic chemicals that can kill off a tank.
