Bio filters and Swirl filters
- Thread starter giford
- Start date
One of the reasons fluidized bed filters were developed, was to make biological filtration more compact. When the swirling media are agitated and collide, this removes older, less virile bacteria, leaving the more robust bacteria to do the job of biological filtration, which is perfect for an average sized aquarium.
But in the end, it's about the amount surface area colonized by beneficial bacteria, as compared to fish and biological load in the tank.
Although my FB reactor is 4ft tall by 8" in diameter, and handles the biological load 4 tanks, it still does not remove the need for frequent water changes.
I have seen FBs that stand 12ft tall and 3ft in diameter used in the large research center for perch farming in my city.
For most aquarists a small FB will be adequate.
