There is a concern if there is a power outage with a fluidized bed. The bacteria uses up all the oxygen in the bed and dies in anywhere from a few minutes to an hour.This produces ammonia that is dumped back into your tank when the electricity returns. Fluidized beds are great for large systems or breeder/dealers that have high turnover of livestock because they have such a huge surface area.
