All you need to add is grow bed media, water and fish.
The Grow Beds/Bio-Filters serve a dual purpose. They provide a bed for holding your plants in place and also serve as bio-filters by providing a home for friendly bacteria (much like those found in soil), which convert the fish waste to nitrates necessary for your plants to grow.
The Grow Bed Media we use and recommend is called Hydroton. Hydroton is pH shipping and made up of very porous kernels of fired natural clay, allowing it to harbor a lot of friendly bacteria. We have field tested Hydroton and find it to be an excellent and easy to work with Grow Bed Media. You can purchase our systems with or without Hydroton.
Deep-Media Grow Beds are 12 inches deep as opposed to shallow-media Grow Beds that are about 7 inches deep. The advantages of Deep-Media Grow Beds are many. There is more media in them to cultivate a greater amount of the friendly bacteria necessary to convert ammonia from the fish waste into nitrates for optimum plant growth and allowing for higher fish stocking density. Due to their depth, these grow beds don’t need to be emptied and cleaned as often because the fish waste naturally breaks down as it migrates over time to the bottom of these deep Beds. This feature alone makes Deep-Media Beds a must.
Our Grow Beds Are Rapid Cycle and well Supported by Strong Steel Stands. These Grow Beds are unique in that they move the water in and out of the Grow Bed at a higher rate than traditional Flood & Drain Grow Beds. This provides lots of oxygen for the vegetable roots to grow stronger and faster. A Rapid Cycle Grow Bed also provides more life-giving oxygen to the bacteria for fish waste conversion, which allows for higher density fish stocking. Our Grow Beds hold lots of Grow Bed Media and water without becoming overloaded. The new Grow Bed Pedestal based Tables are designed to rock stable.
Deep-Delivery Water Rings deposit the water deep into the Grow Bed so the fish waste doesn’t accumulate at the surface of the bed. This allows for better distribution of the incoming water from the Fish Tank.
Proven External Loop Siphons allow for maximum unobstructed growing area. This design allows for the full use of the grow bed without siphon components taking up any of your grow bed planting area.
