What is the recommended maximum limit for Nitrate levels (ppm) when monitoring yabby water quality?
Answer
Below 20 parts per million (ppm)
Water chemistry monitoring is paramount for the survival and health of yabbies, given their reliance on gills and sensitivity to contamination. While ammonia and nitrite must be maintained strictly at zero due to their high toxicity, nitrates are managed differently as they are the less toxic byproduct of the nitrogen cycle. For nitrates, the ideal guideline suggests keeping the concentration low, specifically kept below 20 parts per million (ppm). Exceeding this level indicates that water turnover or waste removal processes are insufficient, potentially leading to chronic systemic health degradation over time, even if acute toxins are absent.
