What's included
Three reagent bottles – A, B and C – dosed to match the original Nitrate Pro protocol.
Not included: comparator, colour disc, glass vial and syringe. Requires the original Nitrate Pro Test Kit hardware and is not a standalone test.
Care and storage
Keep reagents in their original bottles, in a cool, dry, well-ventilated spot away from direct sunlight and temperature swings. Reagent A is corrosive and Reagent B can irritate skin, so keep both capped and out of reach of kids.
Warranty and delivery
Covered by Red Sea's standard warranty against manufacturing defects, in addition to your rights under the Australian Consumer Law, which are not limited or excluded by it. Because the reagents are classified as dangerous goods for transport, they are shipped in their original, sealed bottles.
Common questions
Does this include the comparator?
No. You need your existing Nitrate Pro comparator, colour disc and vial to run the tests.
Can I use this with another brand's comparator?
No. The reagents are dosed specifically for the Red Sea Nitrate Pro system.
