YOKUCHI Mitsuru NO2 Aquarium Drop Test

YOKUCHI Mitsuru Aquarium Test is a line of drop tests for checking the key water parameters in an aquarium. Each kit contains the reagents, the accessories needed for the measurement and instructions for use.

The NO2 test measures nitrite in aquarium water. Nitrite matters most when starting an aquarium, after larger changes to the filtration, after restarting a tank or when the fish are not doing well. An elevated NO2 level can point to immature or disturbed biological filtration. Regular checks reveal nitrogen-cycle problems early, so you can react before the situation becomes dangerous for the livestock.

• Parameter: nitrite (NO2)
• For: aquarium start-up, after filter changes or a restart
• Method: drop test
• Kit: reagents, measuring accessories and instructions
