Monitor two critical parameters with one reliable kit. Red Sea’s Marine Care (MCP) Nitrite & Nitrate Test Kit provides easy, color-based testing to track the nitrogen cycle during tank start-up and to manage nutrient levels long-term. Clear reagents, durable glass vials, and an intuitive color chart make results fast to read and repeatable—ideal for fish-only, mixed reef, and coral-heavy systems.
Two-in-One Testing – Measures both nitrite (NO₂⁻) and nitrate (NO₃⁻) for complete nitrogen-cycle visibility.
Reef-Friendly Resolution – Low-range sensitivity helps detect early spikes that can stress corals and inverts.
Easy Color Matching – High-contrast chart and step-by-step procedure minimize guesswork.
Consistent, Repeatable Results – Precise droppers and stable reagents support dependable readings over time.
Great for Cycling & Maintenance – Track nitrite to confirm biological maturation; monitor nitrate to guide water changes, filtration, or carbon dosing.
Quality Components – Includes glass vials with tight-sealing caps, reagent set, and printed instructions in multiple languages.
Parameters Measured: Nitrite (NO₂⁻), Nitrate (NO₃⁻)
Test Method: Colorimetric (liquid reagents with visual comparison)
Intended Use: Marine aquariums (FOWLR and reef); suitable for ongoing nutrient management and initial cycling
What’s Included: Reagents for NO₂⁻ and NO₃⁻, glass test vials with caps, measuring syringe/dropper, color chart, instructions
Storage & Care: Keep reagents tightly closed, dry, and out of direct light; rinse vials with RO/DI after use
Maintenance Tip: Use alongside routine water changes, protein skimming, refugium or media changes, and feeding adjustments to maintain target nitrate levels
