Sera Nitrite-Test 2x15ml

Nitrite (NO2) is among the most toxic substances for fish in aquariums. It can cause enrichment in the water in case of insufficient biological filtration. The NO2 serum test allows monitoring the nitrite level in freshwater and marine water easily and reliably. We recommend using sera bio nitrivec (freshwater), sera marin bio reefclear (marine water), or sera pond bio nitrivec (pond) in case of slightly elevated nitrite levels. In case of severe nitrite problems, sera Nitrite-minus quickly provides help. Sufficient for approximately 75 measurements.
