Fluidized sand filter

  • We are currently upgrading MFK. thanks! -neo
the purpose of sand filter is for its biological work.. but u also need something to trap the dirt and waste.thats what the mechanical part does
 
I'm thinking of using 3 sand filters with mechanical filtration in the front for my 100g, is it enough biological filtration ?
 
You can only have as much biological filtration as the fish load supports. Fluidized bed filters work and work well but are more complicated than most people want. They also suffer from the problem of very rapid die out in the case of a power or pump failure. (This is true for ALL completely wet bio systems.)

I've used FBF systems before but wouldn't pick one over more conventional methouds. With a sponge filter...bio-wheel...ceramic rings ECT. you can transfur some of the established media as seed material for new aquariums. Thats difficult if not impossible to do with a FBF system.
