Restore natural-seawater chromium with laboratory precision. Isol8:Cr is an ultra-pure, stabilized chromium supplement engineered for ICP-guided trace management within the Captiv8 BluePrint methodology. Used strictly at true trace levels, it supports chromium-dependent biochemical pathways in reef microbiota and calcifying communities—without impacting nutrients or water clarity.
ICP-driven micro-dosing to correct verified Cr deficits accurately.
High-purity, reef-safe formulation for sensitive low-nutrient systems.
Predictable response when added in small, controlled increments.
BluePrint-ready—fits cleanly alongside other Isol8/Aragonite supplements.
Doser-friendly for automated, consistent micro-additions after calibration.
Test first: Obtain a recent ICP analysis and compare chromium to your target.
Calculate dose: Use the label’s dose-to-µg·L⁻¹ relationship for your total system volume.
Split corrections: If a larger increase is needed, divide into multiple micro-doses over several days.
Add in high flow (sump/overflow). Avoid direct contact with coral tissue.
Verify & maintain: Re-test on your normal ICP cadence and convert to a small maintenance dose if ongoing uptake is observed.
Do not exceed label guidance—precision matters with trace elements.
Tip: Time additions shortly after water changes or fresh media swaps for consistent contact time before export.
Maintain core stability: Alk 7.5–9 dKH, Ca 420–450 ppm, Mg 1280–1380 ppm, Salinity 1.025–1.026, Temp 77–79°F (25–26°C).
Log every trace addition and align with your BluePrint schedule.
Avoid simultaneous dosing with strong oxidizers or metal-removal resins immediately after additions.
If running new carbon/resins, dose after media changes for repeatable results.
Safe for reef systems when used strictly at trace levels per testing and label guidance.
Works alongside skimmers, carbon, phosphate media, bacterial programs, and refugia.
Not a medication and not intended for non-aquarium use.
