water qualitity sensors | Details |

On the long term, i'd like to monitor the water quality. The main parameters to monitor are dGH, dKH, pH, dissolved oxygen, CO2 in water, nitrites (NO2-) and nitrates (NO3-). Ideally, we could also measure many parameters (Amonia ->NH3, Amonium ->NH4+ ) that are part of the nitrogen cycle. However, unless the aquarium is not cycled, there should be no ammonia or ammonium. peaks of nitrites may ...
