I am new to aquaponics but have read enough to be a bit perplexed when all my sprouts died at 1-3 inches, I suspected a mineral deficiency or a stagnation problem so I flushed the system a few times and brought home two healthy plants, I didnt have much time so I just set them in the room and did not put them into the system, within 48 hours their leaves turned black, this gave me a heads up that there might be something badly wrong with our air. After doing some internet searches I found out it could be a gas leak so I called the gas company, they found a major carbon monoxide leak that could have killed us and has been very badly effecting my health and to some extent the health of my family. I made a video about it so everyone can see just how aquaponics can save your life:
