Nitrate (NO3) is an indicator for severe organic pollution. The source of this organic pollution should be eliminated, a partial water change provides immediate help.
In the long run, filtering through sera siporax Professional helps avoiding nitrate enrichment.

Sufficient for approx. 60 measurements.



Usage Directions

Monitor nitrate easily, quickly and reliably with the sera nitrate-Test kit.

Algae thrive whereas fish and plants become stunted if the nitrate level is above 50 mg/l. We therefore recommend you to stay informed about the nitrate level in your aquarium or pond. You can lower nitrate levels by adding rapidly growing plants, using a slow flux filter with sera siporax Professional and/or carry out water changes more frequently (provided your tap water is low in nitrate).
