Georgetown student Sarah Harper is constructing an aquaponics system in the Maker Hub space of the university library.
She constructed a model out of Legos, and said that this helped her visualize how the system would work.
It will have a 40-gallon fish tank, and cycle water up to a hydroponic grow tray. The tray will be filled with hydroponic media, and net pots to hold individual plants.
Anacostia Aquaponics helped Sarah with the project as part of our Partnership Program. We’ll check back in once they have fish and plants growing.
Great job Sarah!
Here’s a pic from a recent UDC volunteer day at the P.R. Harris Food Hub near the southern tip of DC.
Volunteers and staff have disconnected the grow-trough drain lines so that the pipes can be cleaned to prevent clogging, and the troughs can be removed and rinsed.
The P.R. Harris hydroponic greenhouse uses this A-frame design to hold grow-troughs vertically and make the most of our limited urban space, while ensuring that plants still receive enough light.
Next to the P.R. Harris hydroponic greenhouse is the aquaponic greenhouse. The aquaponic system is still undergoing mechanical improvements before it is functional. Stay tuned!
Mr. Carroll Bryant looks at his backyard aquaponic system “The Knight” in its second growing season. (It’s named after the Ballou H.S. Knights, across the street.)
The Knight has a 50 gallon inground pond currently with about 15 small goldfish, and one medium size (5-inch) comet goldfish. We covered the pond with weed cloth to prevent excessive algae growth.
Water is pumped up to a 10 gallon grow-bed filled with hydroton clay-media. A bell-siphon returns the water to the pond.
Right now Carrol and his wife Janet are growing green onions and some bok choy. We’ll have to get some more fish weight to really ramp up the growth!
This past Saturday, July 22, Global Aquaponic Systems in Silver Spring, MD held an open house with tours from 12 to 5pm.
On the left we see a trough with some yummy duckweed… a great nutrition supplement for fish.
Global Aquaponic has many beautiful, large striped koi driving their plant growth. The greenhouse is large, and grows produce for local sales.
Read more at their website, or set up a tour of your own!
Remember that ESPN Sportcenter quote: “You can’t stop him, you can only hope to contain him!?!?”… well that also applies to Scott’s backyard aquaponic system in Northeast DC.
Last year we were impressed when Scott told us that during the warm months he grew a SALAD PER DAY for his entire family of 5.
The pic to the right shows his harvest for just one day last week… “EXCEPT for the bigger tomato I already ate.”
And below are media-growbeds with zucchinis, tomatoes, and peppers. Scott keeps fish in his sump tank year round (thermal insulation), and in the warmer months links up his second fish tank, seen here to the back right. Everything you see growing here is from one aquaponic system! Here’s a link to his forum thread in case you are interested in more info: Scott’s aquaponic forum thread.
We just installed our new aquaponic system, The Hootie 2.0, at Iona Senior Services near American U. in NW DC.
The Hootie 2.0 can accommodate up to 8 medium size (.5lb) goldfish or other ornamentals. The fish waste will support a constant growth of herbs and several heads of leafy greens at a time.
The Hootie 2.0 features:
- a 29 gallon fish tank;
- a roll-out plant growbed for easy fishtank access;
- hidden shelf space for electrical connections, an aerator pump, and supply storage;
- adjustable height T5 floursecent light fixtures; and
- an automatic bell-siphon drain in the growbed to increase system oxygenation and circulate water.
Thank You Ashlea Steiner at Iona Senior Services for the opportunity!
And Thank You John Favaloro at Avanti Woodworks for the great craftsmanship and creative problem-solving!
Anacostia Aquaponics is hosting an aquaponics lesson and system build at Cultivate the City‘s H Street Farms.
Click Here For Tickets
This event at Cultivate the City’s rooftop farm will feature three activities:
- Introduction to Aquaponics Lesson: learn about the basics of an aquaponic system; the benefits of aquaponics; and the current state of the aquaponic industry.
- New Aquaponic System Tour: see and discuss the new rooftop aquaponic system at H Street Farms, complete with new tilapia fingerlings! Tour given by the creator and manager of the system, Dan Grant.
- Aquaponic System Build: watch us construct a small, vertical aquaponic system (pictured below). Guests are welcome to build your own along with us to take home, just choose the proper ticket option to cover the cost of materials. We will provide free consulting to make sure you get your system up and running!
The “Aquaponic Build” ticket option will cover all the materials necessary for the physical operation of the aquaponic system for you to bring home! This ticket does not include fish, fish food, plant seeds, or water testing kits.
For any questions about the class or the aquaponic system build, email firstname.lastname@example.org

We found a dirty old crayfish at UDC’s Firebird Farm. We cleaned him up and sent him on his way.
Crayfish are a viable aquaponic crustacean, more popular in Southeast Asia and Australia. Check out Affnan’s description of “Crayponics”.
Affnan also has one of the best bell siphon descriptions, he so cray?
Roy is getting creative in order to catch some tilapia at UDC’s Firebird Farm in Beltsville, MD. UDC operates two aquaponic systems at the farm.
The aquaponic system pictured here holds the fish tanks and filtration units in a large insulated shipping container. Water is sent back and forth to a greenhouse several feet away via underground pipes.
Marquette is feeding goldfish in the new aquaponic system at Houston Elementary School of DCPS.
We constructed a grow-trough light enough to sit on the walls of the 75-gallon fish tank.
Water is pumped from the fish tank up to one end of the trough, and drains back into the fish tank from the other side through a bell-siphon. We have some parsley and green onions planted up there to start.
Thanks to the Alice Ferguson Foundation for funding.
