Fluidized Bed Filter


Recovering Detritophobe
A fluidized filter won't do anything for nitrates. It will convert ammonia to nitrite and nitrite to nitrate, but the bacteria which turn nitrate into nitrogen gas need a different environment.

May be better than bio-balls (not highly oxygenated, so less likely to significantly outcompete LR), but still unnecessary - does nothing for denitrification.
