Refill Aquahometest NO2+NO3

This is the reagent refill kit for the Fauna Marin AquaHomeTest NO2+NO3 kit, restocking the solutions used to measure nitrite and nitrate in aquarium water.

• Measures nitrite (NO2) across 0-1.0 mg/l and nitrate (NO3) across 0-20 mg/l
• Resolution: approx. 0.002 mg/l (NO2) and 0.05 mg/l (NO3)
• Reagent refill only — sufficient for approx. 50 additional tests
• Reuse your existing AquaHomeTest vial, syringes, and color comparator

Nitrite and nitrate swings are early warning signs of a stalled cycle or an overloaded bioload. A reagent refill lets you keep testing regularly through a new tank's cycling period or a livestock-heavy stretch without replacing the whole test kit.

Includes: replacement Solutions A, B, and C for the AquaHomeTest NO2+NO3 kit (vial, syringes, and comparator not included — reuse your existing kit hardware).

Caution: Solution A may irritate skin and eyes. Solutions B and C are highly flammable — keep away from heat, sparks, and open flames. Store out of reach of children.
