I have used fluidized filters for a couple of years now so I thought I would throw my 2 cents in. I have never had a problem with the fluidized beds clogging, but all my fluidized beds have been of my own construction, and all have used a mechanical pref
ilter. They are really rather easy and inexpensive to build, and have done a great job of biological filtration for me. The only problem I have noticed with them (and this problem leads me to believe that they are very efficient at biological filtration
), is that the water exiting the bed can be oxygen deprived and needs to be reoxygenized (is this a word?). If space or noise is a concern, I would highly recommend a fluidized bed, otherwise, a wet dry will do a great job and will not need any extra reo
xygenation.
