Grow Healthy, Nutrient-rich Crops with an AST Aquaponics System
Aquaponics merges aquaculture, the raising of aquatic animals, with hydroponics, growing plants in water. Combined with our innovative filters and filtration systems, your aquaponics environment will be able to grow healthy, nutrient-rich crops and fish in a small footprint, using minimal water.
We have filters perfect for easy home use or large-scale aquaponics projects.
We offer a range of solutions from tanks with integrated filtration: an all-in-one aquaponics system, to efficient filters custom-integrated into your existing tanks and system.

Save Time, Water, & Energy
Our bead filter technology, often used in high density aquaculture, has been adapted specifically for smaller scale aquaponics environments and home use. These filters backwash themselves, simplifying maintenance. Imagine never manually cleaning your filters again! Plus the automated backwash minimizes water loss so your whole system can process as efficiently and sustainably as possible.
Our team of aquaponics filtration experts is ready to help you plan and build your ideal system today.

Recirculating Aquaponic Loop
This is a closed loop where the water recirculates within the system. The water travels through the fish tank, filtration, plant component, and back to the fish tank in a continuous loop. This is the most common aquaponics methodology but comes with some risk. With a recirculating system your treatment options for sick fish or plants are restricted.
Decoupled Aquaponic System
In this type of system, the wastewater does not recirculate back to the fish. This is made possible by our sludge concentrating PolyGeyser® technology that releases dense nutrient-rich water to nourish your plants. The main benefit of a decoupled system is risk mitigation. Decoupled systems are lifesaving in the event of an issue with either the plants or the fish.
In a decoupled system, an operator has the freedom to treat the plants as needed for pest and disease with no harm to the fish because the water does not go back to the fish tank. Also, if the fish require treatment that makes the water bad for the plants, an operator can still choose to treat the fish, purge the contaminated waste and run the plant component hydroponically with fertilizer additions when needed. This gives a lot of freedom and allows an operator to provide top quality care for their fish.
A decoupled system can also be fine-tuned for the fish and plants alike. Plants prefer a lower pH than fish. In a decoupled loop, one can maintain the fish at a higher pH, and adjust the waste stream in the sump to match the ideal pH for the plants.
