Cycling a Fish Tank

Water Testing

The first hurdle has been passed as the ammonia is now down to about 0.25 ppm from a peak of 4 ppm. We're not out of the clear yet, the nitrite is somewhere between 2 and 5 ppm at the moment. The nitrite can be just as dangerous to the fish as the ammonia so it will be important to get the levels down as quickly as possible. 

The light at the end of the tunnel

The good news is that nitrifying bacteria are doing their job and the nitrate is on the rise. The aquatronics sensor system is showing me my slow uptick of nitrate.

It's great to see the system in process as the ecosystem is now ready to start supporting plants. I've been running the aquatronics sensors on 4 aquaponics systems for 6 months but this is only the second time I've been able to capture a tank in the cycling process. It's great to see everything is right in line with the API test kit, and there's nothing better than just opening your phone to check your nitrate instead of shaking the different bottles and test tube and running timers.
