Re: Large tank construction
Fluidized bed filters are biological filters only and should have
mechanical filtration occuring before the water enters the fluidized bed
filter. There are several brands of prefilters available that will trap
most of the particulate matter. Also, keep in mind that neither most
prefilters nor the fluidized bed filter will perform chemical
filtration, which is usually accomplished with activated carbon, which
will capture dissolved organics and toxins. Many aquarists use canister
filters in conjunction with a fluidized bed filter. The canister filter
performs mechanical and chemical filtration then routes the filtered
water to the fluidized bed for biological filtration before it re-enters
the tank.
