Plants Plants absorb the nitrates as nutrients. Plants are usually suspended on floating rafts or in cinder rocks.

Bacteria Naturally occurring bacteria converts ammonia into nitrites and then nitrates.

Water Water pumped through the grow bed is filtered by the plants, and then returned to the fish tank.

tank

Fish Fish are fed food and produce ammonia rich waste. When fish grow to market size, they can be sold and replaced with new fish reared from eggs.

Oxygen Fish breathe in oxygen and breathe out carbon dioxide. Plants absorb the carbon, leaving oxygen-rich water for return to the fish tank.

How Aquaponics Works Aquaponics is derived from two words, aquaculture (raising fish) and hydroponics (raising plants in nutrient-rich water.)


At Sustainable Harvesters, we believe that aquaponics is the future of farming! We trust that this natural farming process is the perfect way to train students and future generations on sustainability, food safety, and food security.

Stay Local. Stay Sustainable. Stay Educated.


AquaEnvi®250

System Components

250ga Cone-Bottom Polyethylene Tank Polyethylene is light and has extreme resistance to the sun and other weather conditions with a useful life of 20 years. This will be the new home to your fish until they grow out.

Raised Media Basin This is the final filtration of the nutrient rich water before it gets to your plants. It is also a good spot for mineralization of beneficial bacteria to occur. This 4’x4’ grow space includes a square flat-bottom polyethylene tank, 5/8” rainbow gravel, and an AquaEnvi® Automatic bell siphon used to raise and lower the water as it passes through the media.

DWC Grow Bed

(Deep Water Culture) Made from high-grade pressure treated lumber and a long lasting Hercuscrim pond liner, this grow bed is where your plants will grow out until it is time for you to harvest them.


Wooden Education Deck

NFT (Nutrient Film Technique) optional

This 120 sq. ft. 12’x10’ deck is a great addition for hosting class demonstrations and makes feeding the fish and checking the water conditions even easier! The deck is surrounded by 3’ railings and includes two 4’x3’ teaching platforms, and steps.

This system is used as a staging area for your plants before maturing in the DWC.This accelerated system allows for extra food production and includes a high grade pressure treated lumber stand.

Bio-filter

Traditional Soil Beds

This is a 55 gallon cone-bottom polyethylene tank with an integrated AquaEnvi® baffle system. The baffle in the bio-filter is used to separate the solid waste before the nutrient rich water enters the system.

The (2) 4’x4’ grow beds filled with traditional potting soil. The grow bed nutrients are supplied by the solid waste extracted from the bio-filter.
