Track the two nutrients that drive algae growth—nitrate (NO₃) and phosphate (PO₄)—with Red Sea’s Algae Control Multi Test Kit. Designed for reef and fish-only systems, this kit focuses on the low ranges that matter for coral coloration and overall water clarity. Clear instructions, durable glass vials, and an easy color comparison system make testing fast, repeatable, and dependable.
Dual-Parameter Kit – Measures nitrate (NO₃) and phosphate (PO₄) from a single box.
Reef-Relevant Sensitivity – Optimized for low-range readings used in modern reefkeeping.
Consistent, Repeatable Results – Stable reagents, precision droppers/syringes, and glass vials.
Easy Color Matching – High-contrast chart and step-by-step procedure minimize guesswork.
Great for Nutrient Control – Use results to guide water changes, feeding, refugium/biomedia tuning, or carbon dosing.
Cost-Effective – Multiple tests per parameter for ongoing weekly monitoring.
Parameters Measured: Nitrate (NO₃), Phosphate (PO₄)
Method: Colorimetric liquid reagents with visual comparison
Intended Use: Marine aquariums (reef and FOWLR); suitable for cycling checks and ongoing nutrient management
Included in Box: Reagents for NO₃ and PO₄, glass test vials with caps, dosing syringe/dropper, color chart, instructions
Storage & Care: Keep reagents sealed, dry, and out of direct light; rinse vials with RO/DI after use
Testing Tip: Test at the same time each week; aim for stable, low nutrients rather than rapid swings
