BioTec Flow-Through Filters

BioTec Flow-Through Filters Filter that screens out course debris automatically

The BioTec Gravity Filters are a multi-stage mechanical and biological filtration system in a compact package, designed for larger ponds or for ponds with high biological load (many fish).

Mechanical filtration allows for the screening of particles and debris which are caught by the 300-micron mesh, which is cleaned automatically at regular intervals. BioTec Gravity Filters are the first and only products on the market to offer automatic debris separation.

Unbelievable filtration capacity for its size!

The BioTec Gravity Filters provide an amazing filtration capacity relative to their size.  With capacity reaching up to 32,000 gallons (ponds with no fish) it is amazing that a product of this size is capable of such large applications. The BioTec Gravity Filters are in a class of their own when looking at this information, coupled with the automatic debris separation feature that is the first of its kind.

Automatic Debris Separation
The debris screen in the BioTec Gravity Filter separates coarse debris and self-cleans at regular intervals. Collected debris is deposited in a tray for easy removal during maintenance. This increases filtration capacity and effectiveness.

Distinct filter zones
BioTec filters feature distinct zones that promote the settlement of the beneficial bacteria responsible for different phases of the nitrogen cycle, increasing the conversion of harmful ammonia in the pond.

Filtration capacity for its size
The BioTec Gravity Filters boast an amazing filtration capacity relative to their size, in our larger product up to 32,000 gallons! This means that you can do more with less, the BioTec Gravity Filters afford you the luxury of a large pond with a smaller filter. With the addition of the PhosLess Algae Reducer your efficiency increases even more, removing harmful heavy metals and other chemicals from the pond environment.
