For those who are interested, my aquaponics experiment seems to be going quite well. We went to my parents’ house for a week, and so the aquarium was unattended during that time. I used a vacation time-release food tablet to feed the fish. One of the fish died shortly after we got back—probably due to the fact that the tank is not really established yet, and I wasn’t there to do water changes while we were gone. The plants have shown significant growth.

You may notice that the setup has been moved next to a window to give the plants more light.

Today, I got an eave trough that I have mounted to the wall under the window. I am going to run water into the trough, and have it drain from the trough into the existing tub. This will allow me to grow more plants!

Here are the roots from one of the tomatoes.
