James and William are retro-fitting an existing aquaponic system to improve water flow in the media bed. Without the extended pipes, one side of the bed would not have adequate water circulation. This could lead to poor water conditions.
In the background we see a hydroponic media bed already growing large amounts of basil and tomatoes. This is because we are still far from an adequate stock of fish to produce enough waste/fertilizer in the aquaponic system, whereas in hydroponics the appropriate nutrients can be dosed immediately.
In the hydroponic system, James’ and William’s improved water circulation is not as important because there is not nearly as much organic material to risk foul conditions. It’s important to understand the trade-offs between aquaponics, hydroponics, traditional soil agriculture, and other growing methods.
For IDEA Public Charter School, the aquaponic system is an invaluable STEM education tool to teach students about the ecosystem of fish, plants and bacteria. But it is important to note that depending on circumstances, aquaponics is not the answer for every growing situation.
A 15-gram goldfish named Jay Wright is the first resident of the Georgetown University Maker Hub aquaponic system.
Sarah is the manager of this system. Woohoo great work Sarah! But she says she will change Jay’s name 🙁
We were very excited to kick off the growing season on the Cultivate the City rooftop last week. Time to get planting!
Here’s a pic of some youngsters with the Hootie 2.0 at the Rooting DC Info Fair
And here is the Anacostia Aquaponics 2018 Rooting DC Powerpoint Presentation.
What: Rooting DC Urban Agriculture Expo
When: Saturday, March 3, 9:00am – 4:00pm
Where: Wilson HS, 3950 Chesapeake St NW, Washington, DC
Why: Sustaining a happy life on Earth!
Anacostia Aquaponics will have our Hootie 2.0 Indoor Aquaponic System set up and running in the Vendor Showroom, goldfish and all. [Barring any technical catastrophes]
Anacostia Aquaponics Director Brian Filipowich will present “Aquaponics in Washington DC” at 10:00am in Room 205. There are many many GREAT presentations all day long! See Rooting DC Schedule
It’s always a great time, and there’s lots of foodtrucks, hope to see you there!
Last week we challenged the IDEA PCS garden club students:
If you can move this entire aquaponic system upstairs to the green room during your 1-hour lunch break, we upgrade to pizza for lunch next week. By the way: all the fish have to survive the move; the system has to be back up and running; and you have to move all the water too (we wouldn’t want to shock our bacteria with new water!)
The students succeeded, great teamwork.
Now onto the next goal: grow $200 of produce with this same aquaponic system by the end of the school year… we’re gonna need some bigger fishies than these goldfish, not to be koi 😉 [foreshadowing]

Today, January 25, Mayor Bowser will announce that the District and other American cities will sign on to the Milan Urban Food Policy Pact (MUFPP), a cooperative international agreement to improve food and sustainability in cities all over the world. Mayor Bowser will sign on to the Pact to “build a more sustainable and equitable food system, shaping future patterns of food production and consumption in the District and America.”

The goal is 200 signatures by the end of January.
The Hootie 1.0 Indoor Aquaponic System was able to grow a string bean with only about 100 grams of ornamental goldfish powering the train.
This string bean was just a test to see if we could grow a decent fruiting vegetable with this 29-gallon system. (Fruiting plants like string beans require more nutrients and are generally harder to grow well). Ultimately, this system is best suited to grow seven or eight quick-growing herbs and lettuces at a time because of the small-ish fish tank and wide media growbed.
We were happy to see that – despite its diminutive size – it was a crunchy and tasty little bean!
The Hootie 2.0 Indoor Aquaponic System is equipped with lighting and improved water circulation. Once that system gets to decent fish capacity maybe we’ll try another fruiting veggie… any requests?
