Aquaculture Filters & Fish Hatchery Systems
Get Solids Removal & Biological Filtration in One Unit
Large aquaculture facility utilizing multiple Propeller Bead Filters.
No matter your specifications, we have the perfect filter solution for your recirculating aquaculture system.
Our filters are designed to be robust and reliable, with few moving parts. They also operate at low pressure to allow the use of low to medium head pumps for energy savings. Experience reduced maintenance, minimal water loss, and improved filtration.
High Density Fish Keeping Made Easy
Our filters easily handle high waste loads without caking or channeling and are designed with few moving parts, making maintenance easy and infrequent. We also offer self-automated filters (FIT System, Polygeyser, Airlift, and Endurance) and controller systems to make routine maintenance more automated.

"[AST] Filters are simple, but very effective. They don't have a lot of components, [but] handle solids and biofiltration very well."

Small-scale Home Aquaculture Project? We Can Help
Small-scale, home tilapia project utilizing the AST Endurance filter configured for airlift operation.
Whether you are operating out of a garage or a backyard greenhouse, AST filters are great for home aquaculture operations. We have a wide variety of filters that can handle varying fish loads.
For systems that need a standalone filter, we recommend the AST Endurance™ Filter (pictured right). It is an advancement of our patented PolyGeyser® technology which features automatic backwash, a small footprint, and superior mechanical and biofiltration.
If you are in need of a complete plug-and-play system with both the filter and tank in one unit, check out the AST FIT System. FIT (or Filter-in-Tank) systems are great for hobbyists getting started with aquaculture or replacing an existing system.
Why Buy an AST Bead Filter?
- Tested technology – over 20 years of research and real-world application have proven bead filtration superiority
- Energy savings – smaller pumps paired with efficient design
- Low maintenance – backwashing is quick and doesn’t require you to get your hands dirty
- Longevity – media never needs replacement and is resistant to clogging and channeling
- Excellent biofiltration – media contains 400ft2 of surface area per cubic foot for the biological breakdown of nitrogenous waste
- Superior clarification – studies show that our filters remove 100% of particles greater than 50 microns and 48% of particles in the 5-10 micron range per pass
- Water conserving technology – our newest filters recycle their own backwash water, drastically reducing water loss!
