Oase Nitrite/Nitrate Refill Kit – Water test for safe pond values
The Oase Nitrite/Nitrate Refill Kit (50662) is an original replacement for the Oase AquaActiv water test system and enables precise measurement of the most important nitrogen levels in pond water.
Nitrite (NO₂) is highly toxic to fish, while nitrate (NO₃) is a crucial nutrient for algae. With this test, you can identify critical water values early and react in a targeted manner.
Ideal for regular water analysis and stable pond care.
