Water testing for pH, Ammonia, Nitrites (already gone) and Nitrates (already present). This is the easy part…system has cycled. No nitrites left. Yipee! Time for fish!
One of our aquaponic friends, Rob Torcellini of Bigelow Brook Farm in Connecticut, has a great video on water testing for aquaponics. Check it out! As he notes in the video, you should use the caps and not your finger when mixing your test tube contents. He built a really cool solar geodesic dome too.
