QuikSand™ Fluidized Bed Biofilters
US and foreign patents
Fluidized bed biofilters are simple, extremely compact, self-cleaning, quiet and easy to use.
Water is pumped up through a bed of sand, "fluidizing" the sand media and providing excellent water/media contact. Fluidized bed biofilters virtually eliminate the need for internal void space, allowing them to pack a lot of surface area into a small space.
The QuikSand™ biofilters will create very little back pressure (never more than 6 psi), allowing the use of low-pressure pumps and even powerheads. UV sterilizers can easily be added after pressurized QuikSand™ filters.
QuikSand™ offers all sizes, from a small aquarium size to a 180-gallon per minute (gpm) commercial unit. All units are made in the USA and come with a one-year warranty against defects. Pressurized models are pressure rated to 40 psi. We have very conservatively rated the QuikSand™ biofilters at .8 grams of ammonia removed per pound of media per day.
FB91, FB92, FB93-2
These high grade filters are self-supporting, as they are mounted to a solid PVC plate. The FB91 has a clear chamber. The FB92 and FB93-2 have opaque chambers with clear viewing ports. These models are pressurized, come with threaded ports for mounting oxygen and temperature probes, if desired. Media is not included, see FB80.
This model is designed for ammonia removal where low cost and low maintenance are important. Nonpressurized, so its water return must be able to gravity flow back to the sump, tank or pond. This is the most economical filter you can buy. Media is not included in price, see FB80.
