The aquaponics system seems to be in a self sufficient state right now. We had one little snafu, but for the most part it’s been running smoothly this month.

Uh oh, the fish are behaving differently
For a couple days, I noticed the fish just hanging out near the bottom of the tank. No swimming about. No rushing to the top when I dropped food in the tank. That’s weird. They always come splashin’ to the top when it’s time to eat.
Eventually, I figured out that the outlet the heater was plugged into wasn’t working. The water got down to 60°, which is almost too cold for tilapia. They started to slow down to compensate for the cold water.
